Rob Kardashian's stunning ex-girlfriend Adrienne Bailon flaunts her hourglass figure as she struggles to contain her ample assets in bold bikini during beach break

She was left bereft when Rob Kardashian cheated on her in 2009.

Yet Adrienne Bailon appears to be well over her heartbreak as she showed her reality star ex- beau just what he was missing as she lived it up at Mexico's Dreams Tulum Resort & Spa on Sunday. 

The 32-year-old actress and singer, who found fame in pop group 3LW, showed off her incredible curves in a boldly coloured, barely-there bikini which struggled to contain her ample assets.

Incredible figure: Adrienne Bailon appears to be well over her heartbreak as she showed her reality star ex- beau just what he was missing as she lived it up at Mexico's Dreams Tulum Resort & Spa on Sunday

Her bikini was certainly unique, perfectly combining super-sexy with bold design and colouring, as the two-piece worked over time to contain her incredible figure. 

The top of the set was a standard balcony bra shape with a supportive halterneck while the trimmings of the number were lined in boldly coloured crochet. 

Emphasising Adrienne's tiny waist, was the huge coloured band around her stomach which showed off her flat stomach also. 

Attached to the bottom of the brightly coloured waistband was a tiny pair of knickers which left very little to the imagination on the stunning star's bottom half.

Before her amble along the beach, Adrienne, who also starred in Disney's The Cheetah Girls, pulled on a sexy sheer beach cover along with a white canvas holdall. 

Her ombre locks were worn in wild cascading curls which billowed over her shoulders and flew in the wind as she larked around on the shores. 

She threw on a pair of turquoise dangly earrings and a stack of bangles, a look which completed the beach babe aspects of her ensemble.

She also shared an adorable shot in which she was reclining in the sun while playfully sticking her tongue out as she chilled out in her black bikini.  

In 2007, Adrienne found love with Rob Kardashian, who is now dating Blac Chyna, and appeared on eight episodes of Keeping Up With The Kardashians as his girlfriend.

Lost love: In 2007, Adrienne found love with Rob Kardashian, who is now dating Blac Chyna, and appeared on eight episodes of Keeping Up With The Kardashians as his girlfriend

Young love: During their relationship Rob got a tattoo of Adrienne's name on his torso

Returning the favor: Adrienne also had Rob's named tattooed on her back (left) and later had it removed (right)

The duo were so enamoured they got inked up with matching tattoos before the disintegration of their love in 2009 when it was unearthed that Rob cheated on her. 

In 2014, she hit out at critics who urged her to take back the troubled star: 'It's common knowledge that he cheated on me, and it always bothered me that people were like, 'Pero, why couldn't you forgive him?'

'Why are women always the ones who have to forgive? If you cheated on a man, he would be like, 'You're disgusting, and I want nothing to do with you.' But women, we're supposed to be like, 'He messed up. He made a mistake.' 

'And, in my situation, it wasn't like, 'Oh my God! I made a mistake!' He strategically planned things out so that he could cheat on me and that to me was so disloyal.'
