Is Rihanna running for president? Because the sultry star can't stop kissing babies!

Over the weekend, the "Diamonds" singer couldn't stop cuddling up to Beyonce and Jamie Foxx's daughters at the Grammys -- and last night the 26-year-old got cozy with her lil' cousin Majesty as she went to dinner at her favorite restaurant Giorgio Baldi in Santa Monica. We think Bad Gal Riri may have baby fever!

Baby Majesty, who is the daughter of Rihanna's cousin Noella Alstrom, was Rihanna's date at the Grammys and now she's Rihanna's dinner date! Not a bad life for a baby!

But don't think have a wee one would change Rihanna's wild ways -- the stylish star still stepped out in sexy heels and an over-the-top vintage faux fur jacket from Donnybrook. Baby or no baby in hand -- this gal can't be tamed!
