Luckily for Rihanna, her early-morning performance on The Ellen DeGeneres Show this morning was pre-taped, so she was able to party all night long post-Grammys. RiRi celebrated her double win for “Run This Town” by hitting the town with rumored baseball beau Matt Kemp, despite keeping mum when Ellen asked if she was seeing anybody new. If both hotties really are dating, then at least Rihanna’s taste in men in 2010 is far more refined than her taste in fashion. Check out the Barbados beauty performing “Hard” and “Don’t Stop The Music” on Ellen amid some wardrobe dysfunction.

Rihanna – “Please Don’t Stop The Music”

Rihanna – “Hard”

A train conductor’s hat? A discarded dress from a 1987 Quinceanera? We almost prefer you just donned a pair of Mickey ears and called it a day.
