Friends: Lisa Kudrow reveals 'bad behaviour' of guest star

‘Friends’ star Lisa Kudrow has revealed an actor made filthy comments towards her when they appeared as a guest star on the hit TV show.

The 53-year-old star played ditzy Phoebe Buffay in the world-famous sitcom and made the revelation during an interview on ‘Watch What Happens Live with Andy Cohen,’ admitting she was shocked and upset at their “bad behaviour”.

Kudrow said: “I rehearsed without makeup most of the week, and then on show night, I’m in hair and makeup, and I was told, ‘Oh wow, now you’re f**kable’.

“That’s bad behaviour, I’d say.”

Lisa didn’t make a formal complaint and instead, she confided in Matt LeBlanc who played Joey., adding: “He’s like a big brother.”

The sitcom ran for 10 series and featured appearances from Alec Baldwin, John Stamos, Bruce Willis, Sean Penn, George Clooney, Billy Crystal, Robin Williams, Brad Pitt, Gary Oldman, Danny DeVito and Charlie Sheen.

Lisa – who was on the show promoting new film ‘Table 19’ – confirmed the culprit wasn’t Charlie Sheen.

Earlier this week the 53-year-old actress poured cold water on rumours suggesting ‘Friends’ – which ended in 2004 – is being rebooted.

She said on ‘The Today Show’: “I don’t see it happening. It would be fun, but what would it be about? Think about it: The thing we liked best about the show was that they were 20-somethings and they were their own family. Now, they all have families, so what are we going to watch?”

Lisa stars alongside Anna Kendrick in ‘Table 19’ about a group of misfits who are on the same table at a wedding.
