Selena Gomez performed in Miami on Saturday night, and the singer broke down into tears when she paid tribute to her late friend, Christina Grimmie.

YouTube star Grimmie, who was also a finalist on The Voice, was shot and killed after her concert in Orlando, Florida, on Friday, June 10. Grimmie was signing autographs at the Plaza Live Theater when a man, now identified as Kevin James Loibl, 27, walked up and shot her.

Gomez dedicated "Nobody" to Grimmie when she took the stage at the American Airlines Arena, and after her teary performance, she apologized to the crowd and sat down at the piano. "When she was 14, we met her – my parents and I signed her," Gomez told the audience. "And one thing about Christina and her family, is that she holds her faith so closely to her. It's not about her religion, and it's not about good deeds. It's just that she had faith. And I don't really understand how this happened, but I would like to dedicate this next song to her."

Gomez's stepfather, Brian Teefey, became Grimmie's manager after discovering the rising star on YouTube, and in 2011, Grimmie opened for Gomez on the North American leg of the "We Own the Night" tour. On Saturday morning, Gomez tweeted the below of herself and Grimmie:

In other tragic news, 50 people have now been confirmed dead after a gunman opened fire at Pulse, a popular Orlando nightclub, which is the worst mass shooting in U.S. history.

Police say the shooter, Omar Saddiqui Mateen, opened fire just after 2 a.m. EST, and after engaging in a shoot out with police, Mateen was killed after 5 a.m. An FBI source told People that the shooter spoke with a 911 operator during his attack, pledging allegiance to ISIS and mentioning the Tsarnaev brothers, who orchestrated the Boston Marathon bombings in 2013. In a speech on Sunday afternoon, President Barack Obama stated, "We know enough to say this was an act of terror and an act of hate ... The FBI is appropriately investigating this as an act of terror," he said. "We will go wherever the facts lead us ... What is clear is he was a person filled with hatred."

Kim Kardashian looooves showing off her post-baby body, and seeing as she looks like a total pinup, we're totally on board with this! Of course, it's a wee bit tacky that she's promoting husband Kanye West's clothing line, but her caption ("The Wife of Pablo") kinda made us crack up...

Over the weekend the 35-year-old reality starlet posted the photo above on Instagram, and it appears as though it was snapped on her recent getaway with Yeezy and the kids. After celebrating their wedding anniversary in Europe, the family jetted off to an undisclosed tropical location to celebrate the rapper's 39th birthday.

"Happy birthday to my best friend! I usually would be scared for us getting older but as each year passes, I'm just happy we have more time on this earth together," Kim wrote in a recent social media post dedicated to her hubs. "I love you so much and hope this year brings you so much happiness."

West has confirmed that he'll go on tour to promote his latest album, and while Kim and the kids will likely be joining him for some dates, we have a feeling the fam wanted to spend some quality time together before he hits the road...

Cody Simpson and a male pal went to the Nice Guy in Hollywood on Friday evening, and it looks like the two had a blast on their boys' night out. Cody was behind the wheel of his immaculately restored 1962 Ford Falcon Squire Wagon, which he's had (and been obsessed with) for about six months now.

Last we heard, Cody was dating model/actress Sierra Swartz, but we haven't seen the Aussie singer and his latest flame together in a few weeks. After their love fest at Coachella, we're wondering if things fizzled out? We checked out her Instagram, and it seems like the only thing she's been posting photos of are her boobs and summer outfits...

Zayn Malik cancelled his appearance at the Capital Summertime Ball at the Wembley Stadium in London on Saturday due to anxiety, he shared on Twitter.

"To all those people who have been waiting to see me perform at the Capital Summertime Ball today," the singer wrote in a lengthy Twitter message. "I flew into the UK last night to appear in my home country in front of my family, friends, and most importantly my UK fans. Unfortunately my anxiety that has haunted me throughout the last few months around live performances has gotten the better of me … with the magnitude of the event, I have suffered the worst anxiety of my career. I cannot apologize enough but I want to be honest with everyone who has patiently waited to see me, I promise I will do my best to make this up to everybody I've let down today. I know those who suffer anxiety will understand. And I hope those who don't can empathize with my situation."

Interestingly enough, former fiancee Perrie Edwards and her band, Little Mix, performed at the show. Lately the former One Direction star's love life has been a bit of a roller coaster, having split from girlfriend Gigi Hadid, only to get back together about a week later. The two were photographed holding hands in New York City on Friday night, so it appears as though Zayn is hanging in there.

And they expect us to believe that they're NOT back together?!

On Friday night Kourtney Kardashian and Scott Disick gathered up their three children and hopped on a private jet, and he was doing a paid appearance at 1OAK in Las Vegas, so it seems odd that the fam would be tagging along. So what were they up to?

Kourt and Scott took Mason, 6, Penelope, 3, and baby Reign, 17 months, to see Cirque du Soleil’s The Beatles LOVE show at The Mirage, and after that they tucked their youngest kids in to bed and brought Mason out for dinner at Stack.

“Scott led the family in while Kourtney, wearing a black dress, held Mason’s hand as they arrived,” a source tells Us Weekly. “Despite being so late, Mason was excited. He was a rock star. He skipped and jumped as he walked in holding hands with Kourtney. They were relaxed and very loving. They were out to have fun as a family and made sure Mason did too.”

The duo split last July, and though Scott has been linked to a string of new love interests over the last year, it doesn't seem as though he's dating anyone at the moment. Hmm...do you think he's back with Kourt?

Blac Chyna rolled around town in her silver Range Rover on Friday afternoon, and while we weren't surprised to see the Armenian flag on her fancy whip, we are wondering how on earth the pregnant starlet was able to see! Blac had her face completely covered up with a small blanket when she pulled up to the Kardashian family compound in Calabasas.

It's been confirmed that Blac and hubby-to-be Rob Kardashian got their own reality show, and it sounds like it's coming at the right time. While Rob has plenty of money (and Blac is undoubtedly getting some financial assistance from ex Tyga), rumor has it Blac's demands are practically putting Rob in financial ruin!

According to OK! Magazine, “Blac’s proving to be a very expensive proposition for Rob, who’s having to pay for extra security, prenatal massages and treatments, new made-to-measure clothes for her that needs to be updated every second week and even her ‘Keeping Up with the Kardashians’ surgery regime."

"He’s shot himself in the foot by buying her a gift every week of her pregnancy so far and is now obliged to keep it up to the tune of several hundred bucks a week," a source added.

Kelly Osbourne arrived at Los Angeles International Airport on Friday night with her Pomeranian, Polly, and on Thursday the starlet brought her pooch as her date at the amfAR Inspiration Gala in New York City. Earlier in the week Kelly posted several photos on her Instagram page protesting the Yulin Dog Meat Festival, so clearly there's a reason why Ozzy's daughter is parading her pup around.

In an interview with Humane Society International, she described the festival as “one of the most sickening things in humanity." She added, “When you see these videos of them viciously beating these dogs whilst they’re at a 'festival', that’s not a festival, that’s a massacre, that’s a dog genocide.”

Kelly also encouraged China's younger generation to take a stand against the festival. “You have a voice and it’s a powerful voice, and it’s a strong voice and if you use it towards something that is good like this, you could make it stop," she said. "Be the change.”

Christina Milian was snapped smoking a cigarette and hugging a very attractive (and shirtless!) mystery man when she arrived at a friend's Hollywood Hills pad on Friday afternoon. He may not have been wearing shoes, but we're pretty sure his rock hard abs totally make up for that. And um, what about those Lil' Wayne reconciliation rumors? Seems like Christina is way more into snuggling up to this dude!

Milian and former beau Lil Wayne in January for the second time after she caught him cheating, but he's hinted that the two still have a shot. In his remix to Drake's single "Hype," Wayne raps, "You see my team is right next to me/You don't see Tina right next to me/I thank her for takin' my breath from me/But the second me gon' be the better me." And then, during an interview with Hot 97 earlier this month, Milian said of a reconciliation, "I'm not gonna count that out. I won't count that out. There's a possibility that could happen. You never know."

Sounds like they're both playing the field!
