Erin Heatherton "Floral Bikini" curves in Hawaii

Leonardo DiCaprio was the Nineties heartthrob that set pulses racing as baby-faced Romeo in the tale of two star-crossed lovers.

However, the A-list actor was looking a little portly during a recent holiday on Hawaiian shores.

Yet judging from the scenes in which girlfriend Erin Heatherton, 23, appears totally besotted with her 37-year-old beau, it's unlikely Leo will be taking the weight gain to heart.

Nevertheless, The Basketball Diaries star did seem a little body conscious by keeping his white T-shirt firmly in place even while taking a dip in the sea.

Despite several kissing interludes and tender scenes where Leo helped top up her layer of sunscreen, the getaway wasn't exactly a romantic trip for two.

Instead, the celebrity pair were joined by Leo's good friend and Spider-Man star Tobey Maguire.

Leonardo appeared to have whisked his young beauty away for an Independence Day vacation, coinciding with a break from his latest project Django Unchained.
