Kourtney Kardashian daughter Penelope infant studio Burbank

They must have been taking care of voice-overs!

Kourtney Kardashian and her infant daughter Penelope hit the recording studio today, and the reality starlet looked gorgeous in a chambray top and maroon Isabel Marant high tops. Her little girl has one hot mama!

The mother-of-two covers the latest issue of Us for her 44 pound weight loss, but her sister Kim's pregnancy announcement totally stole her thunder! And clearly the tabloid isn't too happy about being duped!

"Us paid for the Kardashian exclusive; they are livid now. After all the press they've given the girls, they're furious. Clearly Kris Jenner knew about this. She negotiated Kourtney's deal with them. They've given the family millions over the years for exclusives; they expected at least the first tip," a magazine insider told Daily News.

Whenever a Kardashian is involved, there's bound to be some Kash!
