Justin Bieber hiked Runyon Canyon in Hollywood on Saturday, and when our photographers snapped him on the way down, the 22-year-old pop superstar whipped his t-shirt off and flaunted his tatted up guns -- and abs. Wheeee!

Biebs was in a great mood, and while he wasn't joined by lady love Sofia Richie, we have a feeling he'll be spending the rest of the weekend with her. After all, following their romantic getaway to Cabo last week, they've spent the last few days apart, so they're def due for some couple time. On Friday she was spotted out and about with dad Lionel Richie, and the previous night she went to dinner with a male pal while he hit the clubs.

Of course, it's so much harder to keep track of him now that he's deleted his Instagram account. Can he please get that back up and running? We miss his shirtless selfies and the candid snapshots with Sofia...

Seems like Tyga is playing musical chairs when it comes to the cars in his garage! TMZ reported that a repo man collected the rapper's Ferrari the other day after he failed to make a few payments (though Tyga and lady love Kylie Jenner appear to be contesting that story), and now the website claims that the rapper's $2.2 million Maybach was ALSO repossessed. A bad week to be King Gold Chains! Well, allegedly...

Luckily for Tyga, Kylie came to the rescue and bought him a brand new Bentley a few days ago. While it was reported that the two were shopping for the luxury ride together as the Ferrari was being repossessed, it turns out Kylie was trying to surprise her man.

“So, fake stories came out today,” she said in a Snapchat clip on August 31. “The blogs almost ruined it and said me and T were at the Bentley dealership when really it was only me. And I had to lie to T and say, ‘I have no idea, T, what the story is. I was not at a Bentley dealership.’ But I was!" The surgically-enhanced teen reality queen shared a video of a joyous Tyga receiving his gift, and he said, “I’m speechless right now!"

Despite reports that the vehicle was repossessed, Tyga seemed to suggest that it was all part of an elaborate prank devised by Jenner. “When ur lil baby cops u the Bentley truck and hides your Ferrari. Guess I can’t be mad,” he wrote alongside to a pic of his new car. Hmm....

Caitlyn Jenner went to Starbucks in Calabasas on Friday afternoon, and the transgender reality starlet rocked a dressy sweater and cuffed jean shorts, along with a giant black leather purse. We'd love to know what's in her bag! And props to her for seamlessly making the transition from summer to fall fashion...

As you may have heard, I Am Cait won't be returning for a third season on E! due to low ratings, but the former Olympian will still make appearances on Keeping Up With the Kardashians. Still, we're not sure how often, because it seems like she's been absent from numerous family gatherings, including Kylie's recent birthday bash at The Nice Guy.

While she may be on shaky ground with some family members, Rob Kardashian, who hadn't spoken publicly about his stepdad's transition before, recently revealed that he supports her. "I know how it can be to feel uncomfortable in your own skin," he told People magazine. "Everybody has their own issues. As long as Caitlyn is happy, I'm happy."

Either he's jet lagged from London or still down in the dumps over that heated exchange with estranged wife Jennifer Garner earlier this week!

On Friday night Ben Affleck arrived at Los Angeles International Airport, and the actor looked exhausted -- and like he's put on a few pounds. Whatevs, he's still a stud, and he also made the time to greet fans and sign a few autographs, so we totally adore him for that!

Still, we're dying to know what happened when we photographed Ben and Jen having a VERY tense reunion at the kids’ karate class last week. After having a discussion about something, Jen was seen wiping tears from her eyes, and Ben had a pretty guilty look on his face. I mean, he's already (allegedly) banged their former nanny, so what's he done now?!

Before catching a private jet to Las Vegas for the evening to host a party at 1OAK, we caught Scott Disick cruising around Los Angeles in his bright blue BMW i8 electric sports car to meet a friend for lunch. Later in the day the reality star jetted off to Sin City, but get this -- at the club, Scott told People that he is thinking about quitting the nightlife scene!

"I feel like [1 OAK] is a second home but I'm thinking about retiring from the whole appearances. I've just been doing it for so long," he told the mag. "They just feels like it's so repetitive. I love them and I'm gonna try to have a good night, as I love it here, but part of me feels like I just can't keep doing these for the rest of my life either. It's just starting to feel like Groundhog Day. I don't know if I can give the people what they want anymore."

Funny, because he seemed to be having a blast when he sipped on Grey Goose cocktails took the mic at the club, where he stayed until 2:30am. Guess he's really earning his keep:

When asked what else he'd do, LD replied, "Just trying to make more money during the day and not at night." We're just wondering if this has something to do with the fact that estranged baby mama Kourtney Kardashian recently hinted that the two might be getting back together. "The idea of having my family together is amazing, but it’s not the way things ended up," she revealed to Cosmo. "They may end up there. I’m not sure. To me, it’s in God’s hands. If it’s meant to be, then things will line up … We definitely tried for a long time. But relationships are exhausting! Being able to focus on the kids and me right now is good. We say to each other all the time, ‘I’m the coolest ex-girlfriend/baby mama you could ever ask for!'”

Were so curious to see where this goes, especially if the Lord quits his super lucrative career as a party host!

Chris Martin took daughter Apple and son Moses to the fair in Malibu on Friday, and we're kinda surprised that his ex-wife Gwyneth Paltrow wasn't there with him! After all, the two have stepped out (and gone on trips) with their kids a handful of times since they announced their split two years ago. Interestingly enough, the former couple only recently finalized their divorce...

Last March Gwynnie chatted about their modern family with Glamour mag and said, "We spend a lot of time together ... Last night he got in at midnight and slept here so he could surprise the kids in the morning, we could all have breakfast, and he could take them to school. So ... we're not living together, but he's more than welcome to be with us whenever he wants. And vice versa: I sleep in his house in Malibu a lot with the kids. We're still very much a family, even though we don't have a romantic relationship. He's like my brother."

A modern family indeed...

Rihanna and Drake are back together, but she just took things one step further by getting a tattoo in honor of her on-again boyfriend. Does this mean it's more serious than ever before? We hope so, because we love Champagne Papi and Bad Gal RiRi together!

So here's the backstory: After Drizzy presented his lady love with the MTV Video Vanguard Award and professed his love to her onstage, the rapper congratulated RiRi by posting a photo of the two, in which she is seen holding a camo print shark stuffed animal. (You can barely see its nose in the snapshot above, but trust us, it's there.) Drake reportedly bought the adorable toy for RiRi when the two visited the Toronto aquarium earlier this summer, so clearly this has been going on for a while...

We're not sure if the camo print shark marks the day the two made things official, but Rihanna went to her tattoo artist Bang Bang and got it inked on her ankle. Bang Bang posted a photo of Ri's latest ink, and naturally she's wearing a pair of oh-so-sexy lace-up sandals...

Best big bro ever!

On Friday Justin Bieber took his little sister Jazmyn shopping at American Girl Place at The Grove in Los Angeles, and the pop star held on tight to her hand as they scooted around the store. Before treating his little sis to a shopping spree, Justin made a stop in West Hollywood for some gas and briefly chatted with photographers.

Between Jazmyn and girlfriend Sofia Richie, it doesn't look like Biebs has room for any other women in his life. This is a first! After ex Selena Gomez cancelled her tour, Biebs hasn't even reached out to her! Not surprising since they're in the middle of a massive social media dispute, but dayum! “He is doing his own thing and his own tour and he isn’t spending his time worrying about her,” a source tells Hollywood Life. “He’s really loving his relationship with Sofia, and as long as Sofia is in the picture it looks like it will remain that way.”
