Jack Black is living large these days!

The 41-year-old funnyman, who is seeing here running errands with wife Tanya Haden in Beverly Hills, is set to host the 2011 Nickelodeon Kids' Choice Awards on April 2.

Black has a busy upcoming movie schedule with Kung Fu Panda 2, Bernie, The Big Year and The Muppets opposite Jason Segel and Amy Adams.

Find out how Jack describes his upcoming role in The Muppets ... after the jump.

Jack Black is hilarious on screen, but on the red carpet, we'd rather look at gorgeous Emily Blunt. She looks stunning in this Roksanda Ilincic dress and Jimmy Choo heels. We wouldn't expect anything less from the fashionable Ms. Blunt.

Mr. Black, and his co-stars, hit the red carpet for the Gulliver's Travels premiere at the Grauman's Chinese Theater. Only Jack can get away with wearing a shirt that reads, "I See Small People." Loves it!

Gulliver's Travels hits theaters on Christmas Day. We'll see if audiences are feeling jolly ol' Jack's comedic holiday vibe.

Jack Black was spotted leaving a music store in Studio City on Friday with a cello case! Has the actor/musician decided to go classical?

Nah, he's just being a gentleman and carrying it for his wife Tanya, who's the cellist in the family. Who knew?

...and Jack, uh, walking his bike.

Hey, as long as he's wearing a helmet, it's okay by us!

...jump!

Tropic Thunder star Jack Black was spotted playing with his son Sammy at a Beverly Hills park over the weekend. Hey, who better than your father to teach you to look before you leap!

Jack Black may be one of Hollywood's more, er, rotund stars - but it looks like his son Sammy's decided to help him shed a few pounds!

We caught the Tropic Thunder star horsing around with Sammy in the park while his wife Tanya Haden looked on approvingly. Sammy really gave Jack the runaround, too - seriously, we're exhausted just watching the two of 'em go at it!

TomKat weren't the only celebs at the Tropic Thunder premiere last night (which we hear is hysterical), actor/director Ben Siller, Robert Downey, Jr., who apparently steals the show, Jack Black (with what looks like a jacket painted with bolts of lightning!), and Matthew McConaughey, who replaced Owen Wilson in an uncredited cameo also showed up to walk the red carpet!

This time, luckily, Matty left Levi at home, but check out all the stars at the Tropic after party at Crown Bar!

Tom and Katie, natch...

...as well as Jack Black, Danny R. McBride, Susana Hoff and her husband Jay Roach!

No question that Jack Black is a funny man, but it's also nice to see him just be a regular 'ol dad!

We caught up with the father of two at the park with his fam this Friday - looks like the group is having a fun time! Think Jack all took 'em to a showing of Kung Fu Panda later on?
