Who knew these two were BFFs? Guess they've stayed in touch since filming Forgetting Sarah Marshall in 2007!

Over the weekend Russell Brand was snapped picking up Jason Segel in his black Range Rover, and the guys looked thrilled to be spending time together. Maybe Jason will set Russell up with a nice lady? Or are these two going to be working on a new project together?

Speaking of work, Russell recently confessed that starring in the Arthur remake back in 2011 was not one of his best career decisions. “I didn’t know a lot about script construction," he tells The Sun. "I know more now. I was just embracing things enthusiastically. I thought I could do anything. I felt a little bit bruised [after the bad reviews]. I felt I’d made a mistake.”

We guess work was calling him back to L.A.!

Jason Segel departed JFK airport Sunday after spending quality time with girlfriend Michelle Williams and her daughter Matilda in the Big Apple, and the How I Met Your Mother star seemed in a cheery mood despite having to leave his ladies behind!

The A-list couple recently returned from a Mexican vacation with the Oscar-nominated actress's pal Busy Phillips, and even though they were accompanied by friends, we were kind of expecting the blonde beauty to come back from the holiday with a ring on her finger. The I Love You, Man actor seems to have found The One in the Dawson's Creek star, and has assumed the role of father figure in her little girl's life.

We think it's only a matter of time before we hear wedding bells!

The funny man looks like he's becoming a family man!

Jason Segel, girlfriend Michelle Williams and her daughter Matilda had a relaxing afternoon checking out all the wildlife at the Bronx Zoo today, and they looked like quite the happy trio!

The Oscar-nominated actress and the Forgetting Sarah Marshall star went public with their romance in March, and it appears the relationship is moving at lightning speed! The 32-year-old actor has stepped in as a father figure to the blonde beauty's 6-year-old with the late Heath Ledger, and it appears his fatherly instinct makes his girlfriend completely smitten!

Not only is Mr. Segel doing a wonderful job with daddy duty, he's also already meeting the folks! Along for the zoo day were the My Week With Marilyn star's parents, Larry and Carla Williams.

We hear wedding bells!

This has to be one of the cutest couples in Hollywood!

Michelle Williams and Jason Segel have moved at lightning speed since first getting together after being introduced by the Dawson's Creek star's bestie Busy Phillips, and although we primarily catch them around her place in Brooklyn, the lovebirds are currently enjoying romance on the West coast!

The Forgetting Sarah Marshall star has really stepped in as a father figure for his lady love's daughter Matilda, and with rumors swirling that the funny man might not reprise his role on How I Met Your Mother when it comes back for its ninth season, we have to wonder if he's clearing up his schedule to become a family man and spend more time with his main gals?

We haven't see Miss Williams this happy in ages!

It was rumored that Jason Segel had popped the question to girlfriend Michelle Williams at San Diego Comic-Con last weekend, but there was no sign of an engagement ring as the happy couple landed in NYC with her six-year-old daughter, Matilda Ledger, on Saturday afternoon.

The adorable trio have been spotted on numerous outings together, and Segel has become a father figure to Matilda, whose father Heath Ledger, suddenly passed away when she was just two years old. The Muppets star has also proudly shown off a sticker with a picture of Michelle on the back of his iPhone, so he can see her beautiful face everywhere he goes!

The My Week with Marilyn star was actually introduced to Segel through her BFF Busy Philipps, and the pair remained friends for several years before taking their relationship to the next level. Think there are wedding bells in the couple's near future?

Despite the fact that they're rarely ever seen out together, there's no denying Michelle Williams and Jason Segel are an item!

The adorable pair met for a romantic dinner date in NYC on Thursday night, and the usually demure My Week With Marilyn star looked sexy in a low cut LBD, while Segel looked dapper in a black suit and tie.

The pair have been dating since the beginning of the year, and sources close to the Forgetting Sarah Marshall star say he's totally in love with Michelle, and has even become a father figure to her 7-year-old daughter Matilda, who lost dad Heath Ledger when she was just two.

Segel has only opened up once about Williams, telling Extra during an interview in April: "I think we would just very much like to be happy. That's all I'm going to say about it."

Hollywood Boulevard was overrun with scruffy puppets Saturday as Jason Segel and Amy Adams took to the red carpet with their friends and co-stars to celebrate the opening of The Muppets.

Everyone's childhood favorites -- Miss Piggy, Kermit and the gang -- star in the new film which finds the old pals coming together to save Muppet Theater, which a greedy oil tycoon is threatening to take over and destroy.

The film opens November 23. Check out the trailer ...

Amy Adams and Jason Segel stopped traffic while filming The Muppets in the streets of Hollywood.

Whoa! Check out those moves. Good thing Amy trusts Jason completely because he appears to be quite the hands-on kind of dancer ... and who knew Ms. Adams was so flexible?

The Muppets arrive in theaters on Thanksgiving. We're sure the kids are going to love this one!
