Swift's rep, Tree Paine, tells PerezHilton.com:
Wow. Wow. Wow.
Kanye is straight-up INSANE!!!!!
Sounds like someone’s living a Teenage Dream!!
Katy Perry and her new BF, Robert Ackroyd, can’t seem to get enough of each other lately!
The new lovebirds were spotted at Chateau Marmont last night, having dinner with some friends on the patio!
Katy wore some casual jeans and looked really happy with the Florence + The Machine guitarist!
Sweet! She's introducing him to her friends. Such a big step.
When do we get to meet him, gurl?!
