Tyra Banks helped strip her new "America's Next Top Model" costar Robert Evans of his clothes today on "Good Morning America" -- but is she doing the same in real life too?!

Rumors started spreading that the two were hooking up when the 38-year-old supermodel posted a photo of her and the much-younger Rob in Jamaica together earlier this summer.

Though the two have some good chemistry together and she clearly likes taking his clothes off, they swear they're just friends.

See what they had to say about the rumors this morning on "GMA" -- plus see video of Rob's strip show:

24-year-old Evans is only one of the new faces this season on the show.

With Nigel Barker, J. Alexander and Jay Manuel all gone, Evans and PR guru Kelly Curtone join Tyra on the judging panel. Stylist Johnny Wujek was tapped to replace Manuel.

The new season kicks off tonight on The CW. Will you be tuning in?
