Avril Lavigne sum41.jpg We've heard of stepping out for a bite - but Deryck Whibley just took things one step further!

Last night, Avril's hubby had been working in Los Angeles with a couple of pals when their group started feeling the need to feed. So where did they end up - Mr. Chow? Koi? In & Out? Try Vegas!

Yes, that's right - Deryck and his crew hopped on a jet and headed for Sin City for dinner! And, of course, once they'd eaten their fill, they couldn't resist indulging in a little Vegas-y behavior; after hitting up the Palms Casino, they headed over to Blush, the nightclub operated by Wynn. They were having so much fun that the usually-reticent Whibley even let a photog snap a shot of him and his buds!

Of course, since Avril's currently in England as part of her world tour, she couldn't exactly drop in to join the boys for dinner. After all, Avril's commute would be even longer than Deryck's!
