Jennifer Aniston looks beautiful in a dress. Nike is hoping she also looks dashing in its sneakers.

The footwear giant (maybe you've heard of it?) hasn't confirmed the amount of the deal it's expected to agree on with the Friends star - but sources say it may be the largest sum ever paid by the company for a celebrity endorsement.

Fortunately for Aniston, now when people tell her to "Just Do It," they won't be referring to marriage with Vince Vaughn.

The campaign is reported to be international in scope. It might also include a Super Bowl 2007 spot. Perhaps halftime performer, Prince, can somehow be involved. As long as he leaves all skimpy yellow outfits at home.

Rumors are state that Nike is also working with Eminem, who will design an autographed line of Air Max training shoes to be auctioned off for charity.
