Christina Aguilera made her debut at the ACM Awards last night, and from her presence to her pipes, she totally owned the stage!

The 34-year-old singer squeezed her sexy body into a white Roberto Cavalli gown, and though she went heavy on the makeup, her platinum locks were relatively tame. Xtina and Rascal Flatts' Joe Don Rooney and Gary LeVox performed "Shotgun," and the group also sang the band's hit, "Riot."

"I really love the song. It speaks to long-lasting love, the roads it takes, the turns it makes and how it lasts forever," she told People of "Shotgun." "When I perform it, I really think of that older couple who have been through it all and who have stood the test of time with the changes that their relationship goes through."

Taylor Swift went pop, but can Xtina go full country? I mean, she is a guest star on ABC's Nashville, so it's not totally out of the cards!

Taylor Swift's mother Andrea presented the superstar singer with the 50th anniversary Milestone Award at the 2015 Academy of Country Music Awards on Sunday evening, and we got a bit teary when we heard her speak!

Early this month Swift revealed that her mother was diagnosed with cancer, and she said in a statement, "Thank you for caring about my family so much that she would want me to share this information with you. I hope and pray that you never get news like this."

Taylor's mom started off by discussing the starlet's passion for music. "I've watched this milestone artist from the time she was a tangled-haired little girl growing up on our farm, full of imagination and creativity, until right now, as she prepares for her next world tour," Andrea said. "And ever since then, her favorite thing in the world to do has been to write a song, tell a story, play guitar or piano. And I've seen those things carry her through every emotion, every experience in her life, good or bad."

Andrea grew emotional and added, "Like many of you with children of your own, I am a very proud mom. So I'd like to thank the ACMs for honoring her in this way, but I'd also like to thank the entire music community for taking such good care of her. And to the fans, I know you love her as I love her, and for that I thank you eternally." Awww!

When Taylor took the stage she gave her mom a huge hug, and she went on to thank the country music community and all her fans. In case you missed it, check out the video below!

Gorgeous girl!

Blake Lively rocked a red hot Monique Lhuillier gown for the New York City premiere of The Age of Adaline, and we can't stop staring at her perfect physique. How is it that she gave birth just four months ago?!

The 27-year-old actress posted a photo of her getup on Instagram later and wrote, "Workin Emoji Chic. It's the new thing. Watch out Norm Core," along with fourteen of the infamous salsa dancer emojis. Our fav!

Lively stars as Adaline, a woman who is "rendered ageless after an accident." In a recent interview she revealed that after her hit CW series Gossip Girl wrapped, she wasn't feeling any scripts -- until she got her hands on this one.

"I feel like magic doesn't exist much in films these days, unless it's a superhero movie or has a wand," she told Very Aware. "But that magic in humanity, magic in a quiet film, is rare ... When [movies] like this come along, they're called 'little movies that could.' Adaline is sort of between that, because it's a movie that can reach a broader audience, but it still has that magic and humanity."

We can't wait to see it!

We know teasers aren't supposed to give away too much, but Diane Sawyer is really making us work for those Bruce Jenner interview clips!

ABC has released a new video of Bruce's tell-all interview with Diane, and now the former Olympian gives a soundbite on how he's worried about his gender transition affecting his famous family. "Those are the only ones I'm concerned with," Jenner said of his children. "I can't let myself hurt them."

"My whole life has been getting me ready for this," he said in a previous clip. C'mon Diane -- we want more! Especially now that we know Bruce has breast implants and wants to show off his hot bod.

Bruce Jenner: The Interview will air on Friday, April 24. We'll DEFINITELY be watching!

That was fast!

Over the weekend Justin Timberlake posted the adorable shot of his wife Jessica Biel and their newborn son Silas, and we can't believe how tiny he is -- and how amazing Jessica looks! And though the couple have been pretty notorious for keeping the details of their personal lives out of the media, it seems like they couldn't wait to upload this sweet snapshot!

Silas is already wearing a Memphis Grizzles jersey, and JT captioned the pic, "The Timberlakes are ready!!! GO GRIZZ! #GritNGrind #Playoffs #BabyGrizzROAR." Um, #toocute!

Jessica and Justin welcomed the tiny tyke earlier this month, and last week it was reported that the proud parents plan to raise their little boy in Big Sky, Montana. "Their house is all set up for the baby," the insider tells Us Weekly. "They want to raise him out of the spotlight." Another source added that "Jessica is happiest when she's in the mountains."

We're guessing we'll be seeing more pics of this beautiful family though!

It's a thug life for Taylor Swift!

Green heels and bling for a day out in NYC ... seriously -- do you see that "S" around her neck?! We LOOOVE how Tay accessorizes her preppy look with a gold chain. The snazzy singer dined out at the Spotted Pig in NYC and showed off her thin pins in a matching blazer-shorts combo.

Lest you forget, Taylor Swift fans ... this girl's a thug at heart! ...

Happy birthday, Kourtney K!

The mother-of-three celebrated her 36th birthday in Vegas last night at 1Oak, with hubby Scott Disick (sober, we hope) by her side.

The reality star looks stunning in a short, little black dress, showing off her amazing post-baby bod after giving birth to baby Reign in December.

Meanwhile, Scott didn't look quite so amazing. The newly-rehabed bad boy looked a little bored as he sipped water from the VIP table, according to sources. Kourtney made sure Scott stayed close -- probably wanted to keep an eye on him. And apparently the night went off without a hitch. This time ...

Another day, another inappropriately-sexy outfit for Kylie Jenner at Coachella!

The 17-year-old partied with 25-year-old boyfriend Tyga and sis Khloe Kardashian in the desert heat yesterday, wearing ... well, almost nothing. And she took to Instagram to share her personal snaps with fans. Seriously, though, we wonder if she gets more fan compliments or more haters hate on social media. It's gotta be tough on the ego ... guess that's why she keeps uploading more and more -- hoping to tip the scales in her favor at some point.

Khloe's also partying with a boy out in Indio -- on-again-off-again beau French Montana. She's not so public with her love affair, however -- no pix of Frenchie on Khloe's Instagram! Just Kylie and Kendall (above right) with the caption "Bad Bitches." Such a compliment!
