Troubled EastEnders star Jessie Wallace shocked punters at a Brighton night club when she walked into the men's toilet.

Jessie - who earns £100,000 a year playing gobby Albert Square barmaid Kat Slater in the BBC soap opera - lived up to her brassy on-screen image at a gay club in Kemp Town.

She walked into the gents' loo and peered over the shoulders of four men standing at the urinal, giving each of them marks out of ten.

She told one blushing clubber at the St James's Street venue: "You've got a nice one" and dubbed another "Big Boy".

The soap star then locked herself in a cubicle while her friends stood guard stopping anyone going into the men's toilets.

One of the men she passed comment on said: "I was shocked she was even in the club, let alone in the boys' toilets. She was so much like her character in EastEnders. She kept saying "awright darlin' " in her East End accent.

"There was a massive queue for the ladies so I suppose she couldn't be bothered to wait. All of a sudden she burst in and put her head over my shoulder. It was a bit of a surprise but she was very complimentary to all of us."

A group of photographers were in the club and spotted Jessie.

But when Aaron St Clair from The Argus approached and asked if he could take a photo, the star threw a Kat-style tantrum.

He said: "I really thought she was going to hit me. She went ballistic. I've never had such a bad reaction from anyone before.

"She was telling me where to go and being so horrible, then all of a sudden she turned round and said, 'Come on darling, let's have a good night. Let me buy you a drink'."

An hour later she relented and agreed to pose with Aaron for a photograph.

Jessie stayed in the club until the end of the night and spent the night in Brighton.

It's not the first time the actress has been spotted enjoying the city's gay scene. She travels down from London regularly and parties in gay clubs in an attempt to avoid being bothered by fans.

The BBC declined to comment on her behaviour, saying she had been at the club in a private capacity.

But yesterday the News Of The World revealed that EastEnders bosses were deeply worried about her behaviour following a series of incidents.

Jessie has twice been convicted of drink-driving and during the latest case was branded a liar in court.
