While the bad boys from Boston in Aerosmith might not be the first thing that comes to mind when you ponder child rearing, the Run D.M.C.-aided rap version of their classic tune ‘Walk This Way’ is one of the things you’ll hear in one of the trailers for the upcoming flick ‘What To Expect When You’re Expecting.’

The movie, based on the best-selling book of the same name, features a who’s who of Hollywood’s elite from Chris Rock to Cameron Diaz in addition to Steven Tyler's fellow 'American Idol' judge, Jennifer Lopez. The plot chronicles the lives of five intertwined couples ready to enter the great big scary world of parenthood.

The trailer, seen below, features ‘Walk This Way’ as the theme song for the cast of dads and dads to-be-who’ve dubbed themselves the “Dude's Club,” not to be confused with that other Aerosmith ditty ‘Dude Looks Like a Lady.’ Are you still following? If not, you can follow the Dude’s Group on Facebook and find out everything you ever needed to know about being a dude with a baby.

The movie hits screens on May 18, just about a month before Aerosmith and Cheap Trick kick off their summer Global Warming tour on June 16 in Minneapolis, Minn.

Aerosmith are also chugging away on a new disc. It will mark their first album of original material in more than ten years and according to guitarist Joe Perry the band has no problem finding that creative magic once they hit the studio together. No release date has been confirmed just yet but the band is hoping to have it out by July.
