Rihanna left both her maybe boyfriend and adorable doggie at home yesterday afternoon and got all sexed up to shoot her new music video in LA. Look at her in her badass red leather jacket — it's gonna be a sassy one. Whoever she is or isn't dating, Rihanna's a hot young thing these days. I wonder if she'll make it out to her mentor Jay-Z and Beyonce's rumored upcoming wedding? Perhaps for a reception rendition of "Umbrella" with the groom?
