Are you keeping up with Kardashian sisters Kim and Kourtney?
The pair left their sunny Los Angeles digs – and sister Khloe, who’s got her own show – behind to head to the Big Apple in E!’s latest reality spin-off, Kourtney & Kim Take New York, which premiered Sunday night.
In town to open a SoHo outpost of their store Dash, Kim and Kourtney also found time to have a little fun. Kanye West showed up in Sunday’s premiere to offer his style advice and flirt with Kim, who invited him to attend her 30th birthday party in Las Vegas. He, of course, accepted the invitation.
