Rihanna gets "Louder" while performing on MTV's "The Seven" in Times Square in NYC Nov. 15.

Rihanna hit up London's "X-Factor" show to sing her latest single "What's My Name" and for a very intimate performance of her track "Unfaithful" with "X-Factor" constestant Matt Cardle. Watch the videos below:

After the show, Rihanna was seen flashing the pesky paps and then sleeping like a baby in the back seat of her car, thumb-sucking and all.

I have to say, "What's My Name" is my favorite Rihanna song ever and "Loud" is my fave Rihanna album to date. Not to mention, her stylist and I share the same first name and I love the outfits she puts Rihanna in. I think I'm officially a stan.
