Chloe Green shows off her slim beach body as she relaxes by the swimming pool in a black bikini

Considering her boyfriend's ex-wife has the world's most famous derriere, Chloe Green has a lot to live up to.

However, the Topshop heiress looked like she was on the right track as she holidayed in Miami, Florida, on Thursday.

The 22-year-old showed off her incredible beach body as she sauntered around the swimming pool making sure every inch of her toned body was on show.

The wet look: Chloe looked in good shape as she wore a plain black two piece bikini

Chloe looked stunning in a two-piece black bikini that contrasted well against her tanned torso.

The budding shoe designer accessorised her skimpy ensemble well with a pair of large sunglasses and some silver bracelets.

With her hair pulled up into a tiny bun, Chloe declined taking a full plunge into the swimming pool.

Instead, she simply dangled her legs in the water before retiring to her sun lounger next to her friends.

Chloe's boyfriend Marc Anthony may not have been with her on her sunny break, but he was still clearly in her thoughts.

Last week she tweeted: 'Sooo excited for @MarcAnthony new single to come out next week "Vivir Mi Vida" you guys have to hear it!! Can't wait!! #proudgirlfriend'.

Chloe's relationship with boyfriend Marc Anthony has raised eyebrows due to the 22 year age gap, but the tycoon's daughter admitted that she doesn't let him being twice her age stop her telling him what to wear.

Back to bed: After cooling off her legs in the pool, Chloe returned to her sun lounger to relax

She told Grazia Daily: 'I get the odd question of 'Do you like what I'm wearing?' and I'm like, 'No not really'. Then he says, 'How would you wear it?'. I'll then say, 'Make it a bit cooler - wear it with some trainers and a T-shirt.' He's then, 'Okay, I'm not sure, but if you like it, I like it.'

Meanwhile a source told the publication: 'Chloe doesn't always have great self-esteem and Marc is a mature and grounded father-of-five. He's old-fashioned and they seem to think he'll take care of Chloe.

'He's also got his own money - Sir Philip has been concerned that guys could be after Chloe's fortune, but Marc's got his own singing/songwriting career.'
