Her songs are catchy - will her products catch on too? Rising music star Ke$ha is now the brand ambassador for the Baby-G women’s Casio watches.

Appropriate, you could say, for the singer of "Tik Tok."

Yesterday, the dollar-signed one even made a special appearance at The Manhattan Center for the Casio press conference and to reveal her latest ad.

Given previous Ke$ha pictures we've seen, we half expected the campaign to feature her looking unkempt and mostly unclothed. What a surprise!

Now if only they could improve her ability to sing live the way they can touch up a pic with Photoshop, Ke$ha would be ready for world domination ...

TOUGH AND COOL: Ke$ha is both. And hopefully punctual.
