It seems like we have more pictures of Justin Bieber grabbing his crotch than we do of him walking normally!

The 19-year-old pop star dined at Toscana in Brentwood on Wednesday night with manager Scooter Braun, and he tweeted, "Big dinner tonight. What r u eating?"

Whew! As long as he's not on a dinner date with a new girl ... after handing out with model Ashley Moore earlier this month, we were a little bit nervous about his relationship status! And what's going on with former flame Selena Gomez?

Not only did Biebs pop his head out and flash us a smile, but he chatted about Selena ... and working with Miley Cyrus! Well kinda. He said Selena is "great" and that working with Miley was "great," and when asked who he's going to work with on his next record, he said he's going to collaborate "with the world." Loves it!

Jamie-Lynn Sigler and fiance Cutter Dykstra welcomed a baby boy on Wednesday afternoon.

"Both mommy and baby are great!" the former Sopranos star's rep said in a statement. No word on what they've decided to name their bundle of joy, but we'll keep you posted!

This is the first child for Sigler, 32, and Dykstra, 24, who plays (minor league) baseball for the Potomac Nationals. The couple got engaged in January after a year of dating, and announced that they were expecting the following month.

"The first few months were not fun. I got hit pretty hard, but I feel fantastic now," Sigler told Us Weekly back in April. "It's the most natural thing your body can do. I have no part in anything that's happening with the baby. I'm just kind of a vessel, so it really is a miracle and it really is an exciting time."

Congrats!

Bruce Willis who?

X17 photographers snapped Mel Gibson leaving a private gym with his trainer on Wednesday afternoon, and the 57-year-old actor showed off his buff arms in a black tank top. Seriously ... where did these lethal weapons come from?!

On Monday it was announced Gibson would join the cast of Expendables 3, and it's not like he's going to be replacing Bruce's character, but he's going to be starring opposite Sylvester Stallone and Jason Statham, so he might as well beef up for the big screen!

We still can't get over the news that Ben Affleck is going to be the new Batman, but that's not a bad thing -- we're ALL for seeing the sexy dad slip into yet another superhero suit!

Yesterday afternoon Ben stopped by a pal's house in his neighborhood, and he was sweet enough to buy a cup of lemonade from a young kid on the street. Whoops ... looks like it might have been a little on the sour side!

Ok, but back to Batman ... Ben's pal Matt Damon chatted with X17 about the casting decision, and he later defending his friend's upcoming role in an interview with The Times of India.

"You know, he's not playing King Lear," Damon said. "It's Batman, certainly within his skill set. If anybody saw Argo or The Town, and all the work he's been doing lately, it's way more nuanced and interesting and way more difficult than Batman!"

But don't expect Damon to play Batman's BFF Robin. "I am a little older than Ben. I never saw Robin as older than Batman," Matt added. "Somebody sent me a picture actually (of his face Photoshopped on Robin's body and Affleck's on Batman's). It was really funny. But it's safe to say I won't be Robin."

On Wednesday Lamar Odom stopped by a Taco Bell near the Tarzana home he shares with wife Khloe Kardashian, and he didn't comment on his marital troubles or his alleged drug addiction, but the NBA star WAS wearing his wedding ring!

Lamar appeared to be in good spirits and he even laughed while ordering at the drive-through, but when he returned home to eat, Khloe went to Kourtney's house. Yesterday she was seen without her wedding ring, and while Lamar reportedly returned home on Monday, there are also claims that his teammates and agent attempted to stage an intervention that day as well.

A photographer on the scene tells X17online exclusively:

"Khloe and Lamar spent the night at home together - but that doesn't mean they were in the same bed. They don't appear to be the best of friends right now. Neither was in a great mood when they left the house and they each went their separate ways."

But this is progress, right?

Fun fact: Lamar appeared in a Super Bowl ad for Taco Bell back in 2010. Glad to see he's still a fan!

Who's that girl?! That couldn't possibly be Hayden Panettiere, could it? Debuting blunt bangs, stick-straight hair and a platinum blonde 'do, the Nashville star had all eyes on her vampy new look outside the Late Show with David Letterman in New York.

The petite 24-year-old certainly looks ready for the fall with her edgy style. The actress even opted for ruby red lips, liquid eyeliner to add to the drama. For the late night taping, the former Heroes star selected a skin-tight, body conscious mini-dress and paired them with red-hot ankle boots.

On Nashville, Hayden plays Juliette Barnes, a country crooner and former teen star star who will do anything to replace Rayna Jaymes (Connie Britton) as the queen of country music. Nashville's sophomore season begins September 25 on ABC.

They look more like sisters than mother and daughter! Jessica Alba, 32, and her five-year-old daughter Honor were spotted picking up some goodies at Mrs. Winston's Green Grocery before stopping by Jessica's office in Santa Monica, Calif., on Tuesday. We can barely believe how grown up Honor Marie is looking!

For the girls' lunch, the Fantastic Four star had minimal make up and wore a floral sleeveless blouse and baggy rolled-up khaki pants. Honor is looking like quite the little fashion plate in her polka-dot miniskirt, French girl T-shirt and bow ballet flats.

Jessica and her husband Cash Warren are parents to two daughters Honor Marie (born in 2008) and Haven Garner (born in 2011).

Is it bad that we kind of love it?!

Miley Cyrus and Justin Bieber have collaborated on a new song that was leaked today called "Twerk", and the name of the tune speaks for itself!

The "We Can't Stop" singer is famous for the bootyshaking dance after her disastrous performance at last Sunday's VMA's, and although you would think she would try to distance herself from associations with the dance fad after all the bad press, apparently the song was recorded a while back.

JB's pal Lil' Twist is also featured on the single.

We wonder if The Biebs wishes he could take this back?
