The end of a relationship frequently sparks an image overhaul, so it’s unsurprising that Kelly Brook has committed herself to a dramatic fitness programme.

The 33 year-old, who broke up with Danny Cipriani earlier this year following rumours he had been unfaithful, has thrown herself into a punishing exercise schedule with a personal trainer.

So it’s fitting that the buxom brunette should be seen in skin-tight lycra and fashionable trainers while enjoying time in Los Angeles.

Working it: Kelly was spotted out and about as she walked around Los Angeles in tight black leggings and a tight black short sleeved t shirt that left little to the imagination

Wearing a dangerously flimsy T-shirt with figure-flattering leggings and fashionable black and white Adidas high-tops, the former Big Breakfast presenter boasted an enviable silhouette.

But, although she looked the part, she clearly wasn’t planning on exerting herself too much as she was spotted with her handbag.

Wearing make-up and sunglasses, she also failed to break a sweat on her stroll, keeping her efforts as low-impact as possible.

Buxom: The TV presenter, who is newly single, looked incredibly buxom while out in California

Fortunately, Kelly’s California trip hasn’t all been about health kicks. She’s also been kept busy with some wild nights out with her new pals.

On Monday the star headed to the Staples Centre to watch the Lakers play Denver Nuggets in a NBA match up.

Afterwards, Kelly continued the fun as she joined the equally curvy Sofia Vergara and Elisabetta Canalis for some post-basketball partying with George Clooney’s ex Elisabetta tweeting a photo of the two of them with Denver’s small forward Danilo Gallinari.

LA story: Kelly is also hoping that her time in LA will attract job offers from agents

But the TV presenter is also using the trip to expand her media career. Taking to Twitter recently, she admitted that she has been approached by agents for potential projects.

‘In bed early tonight reading Scripts!’ she wrote.

Meanwhile, here in the UK, fans have most recently seen her strip down for a new campaign to promote the National Lottery.

The campaign is to build excitement for this weekend’s draw where as well as the £10 million jackpot, a further 1,000 raffle prizes of £20,000 are up for grabs.

Best foot forward: Despite her sportswear, Kelly seemed to do little exercise
