Kim & Orlando TOO CLOSE FOR COMFORT!

Should Katy Perry be concerned?! Newly single Kim Kardashian was spotted getting flirty with Katy's fiance Orlando Bloom at an event in Beverly Hills on August 17, where a delighted-looking Orly, 45, was snapped clutching The Kardashians star's hand as the pair shared a laugh.

"I forgot he's with Katy Perry and was like 'this could this be her next man,' commented one fan online.

 But perhaps Kim, 41, was just digging for gossip on her ex Pete Davidson, who she split from in August after nine months together. Orlando and the former Saturday Night Live star spent the past few months together filming upcoming movie Wizards! in Queensland, and there was even speculation that the Lord Of The Rings star had been giving Pete, 28, break-up advice.

But a source says Katy, 37, is still peeved by the pics.

"When Kim was in Queensland with Pete, Katy told Orly she wouldn't trust Kim and was worried she would break Pete's heart," says the insider. "So she wouldn't be thrilled to see Kim all over her man."

ROBBIE & BABS' MOST AWKWARD ENCOUNTER

They're two of the biggest stars on the planet, but Robbie Williams has revealed he and fellow singer Barbra Streisand, 80, failed to recognise each other when they were first introduced by mutual friends during a holiday in Tahiti.

"It was like, 'Hi, I'm John,' and 'Hi, I'm Rob,' and 'Hi, I'm Steve.' 'Hi Steve,' 'Hi, I'm Barbra' - 'Hello Barbra, I'm pleased to meet you.' Nice old lady. Then I sat down next to Barbra. And it was Barbra Streisand. And I was like, 'Oh, ah,"" says Robbie, 48, who admits Barbra didn't catch on as easily.
