Mollie King nip slip!

Mollie King, Una Healy, and Frankie Sandford of the UK girl group The Saturdays all put on their skimpiest bikinis to lounge by the pool of their hotel in Hollywood yesterday, but Mollie was the only one nice enough to flash her nipple. Boy, those other chicks seem like real bitches!
