Battle of the booties! TOWIE's Georgia Kousoulou and Amber Dowding show off their enviably toned posteriors as they step out for dinner during filming in Marbella

The 26-year-old fashion designer and hairdresser Amber, 24, showcased their toned behinds in tiny matching denim hotpants as they stepped out for dinner.

Georgia accentuated her thigh-grazing frayed light blue shorts with a pair of Perspex heels featuring a fur trim.

Sticking to a monochrome look, she showed off her cleavage in a plunging lacy semi-sheer bodysuit.

Sweeping her blonde tresses back into a chic chignon, the reality star framed her eyes with lashing of mascara and smoky shadow.

Meanwhile, Amber upped the stakes in a floral Bardot crop top, which she teamed with stonewash high-rise shorts.

Boasting a deep golden tan, Amber - who recently had a bum lift - added a pair of nude studded multi-strap heels.

Georgia is filming in Marbella for TOWIE alongside her boyfriend Tommy Mallett, 25,

The pair, who have been together for almost three years, appear to be going from strength to strength, a stability that is not often found in TOWIE relationships.

Georgia is known as an advocate for body confidence and when she started in TOWIE, said she was 'repping it for the curvy girls'.

The Essex beauty's fabulous figure is the result of an intensive work-out regime as she previously confessed to MailOnline: ' I've been working so hard on my summer body, and do different exercises with my trainer everyday.

'One day I'll be running around a park, the next i'll be doing boxing and toning.'

Her stunning figure has also spawned a successful swimwear range, Summer Dreams by Georgia K.

She told MailOnline at the launch: 'It's perfect for women with curves. I've always had curves so it's great to be able to embrace them and feel comfortable in swimwear that flatters you.'

Meanwhile, Amber's outing comes after she videoed herself getting a bum lift procedure in preparation for showing off her bikini body.

Amber clad her derriere in just a tiny thing for the procedure, showing off her rounded tush in all its glory as she sought to further improve it with the cosmetic procedure. 

She explained the procedure: 'Today I’m here with Shane getting Marbs ready with my bespoke body treatment. He’s doing the booty lift treatment.'

TOWIE power couple Chris and Amber initially ended their romance back in October last year, after fans of the ITVBe show saw things between them crumbling.

Chris went on to date Little Mix pop star Jesy Nelson, 26. They went public with their romance at the BRIT Awards in February and things appeared so serious he even flew out to the US to join her while the band supported Ariana Grande on her Dangerous Woman tour Stateside.

However, romance fizzled out between them a few months later, with Chris dumping Jesy while she was on tour in the US and telling OK magazine he'd always felt second best.

'I didn’t understand why she was interested in me – I’m just someone from TOWIE,' he said. 'I always felt like second best to Jesy. But that was my issue, not hers.'

TOWIE fans saw Chris and Amber reconnecting towards the end of the last series of TOWIE, following his split from Jesy.
