On August 4, the happy couple got cozy at a pool party in the Hollywood Hills, and Star magazine has exclusive photos of their sexy sizzling swim.
“There was major chemistry between them,” a source at the pool party tells Star of John and Katy. “He was looking down her bikini top, and they were French kissing really passionately. It was like they were on a honeymoon!”
With Katy in a sexy metallic black and silver bikini John couldn’t keep his hands off of the Firework singer.
“John and Katy were all over each other,” the partygoer said.
“They were holding hands and kissing the entire time. Even in the pool, they stuck together nonstop.”
After hanging out with friends there for a few hours, the two left hand in hand.
While Katy was originally giving John the cold shoulder, he’s used his charms to wear her down.
“Katy’s inner circle was anti-Russell and thought she’d learned her lesson about bad boys,” a friend says. “They flipped out after hearing she’s crazy about John — they think he’s far worse than Russell!”
