Kelly Brook slips into a pair of leggy leather trousers as she leaves her boyfriend behind and heads for a rare girls' night

She may have settled into a loving relationship with beau Jeremy Parisi.

But Kelly Brook has reserved time for the occasional girls' night, as she proved on Thursday night with a visit to The Ivy Garden, Chelsea.

Slipping into her leather trousers for the occasion, the 35-year-old made the most of her curves and left her boyfriend at home for the night.

For Kelly, it was a more shy appearance than usual and she lurked in her girlfriend's shadow on exiting the establishment late at night.

She covered up her usually-on-display chest with a loose-fitting red patterned blouse that hung loosely around her middle, despite being tucked into her waistband.

Kelly's signature touch was her sexy leather bottoms that clung to her shape - a newly-slimmed down size 12 figure, thanks to her recent efforts with the New Atkins diet.

Having enjoyed a brief stint in LA, Kelly certainly put in the hours towards sculpting her shape and was routinely seen running, hiking or in the gym.

The brunette is now more regularly seen working out with her French boyfriend Jeremy as she keeps up her fitness efforts.

After all, the pair are attached at the hip and have done very little outside of each other's company in recent months.

Dating since earlier this year, the pair are no living together in the UK since she's appeared to call off her pursuit of Hollywood fame.

Back in London, the brunette expressed her excitement about rejoining the cast of Celebrity Juice, on which she served as a panel member in Holly Willoughby's place before claiming Keith Lemon sacked her.

And although they appear to be friends again, show host Keith recently told The Mirror that he didn't think she and Jeremy were a 'real couple'.

He said: 'I don't know if her relationships are real or not. She's a PR expert, she knows exactly what she's doing and she's brilliant at it. 

'I was in America with her [when she was engaged to David McIntosh] and there were paparazzi everywhere. I was like, "How do they know where you are?" and she said, "They just follow me everywhere". She just laughs it off.

The Celebrity Juice star went on to say that he'd asked Kelly is she was really going to marry David and he says she replied: 'No, no. But it's a nice ring though, innit?'
