9021-Oh my! AnnaLynne McCord wears a cheeky thong bikini as she celebrates 28th birthday... after hinting she's back with Dominic Purcell

Earlier this week she hinted that she's back with Dominic Purcell by sharing a cosy photo with him and calling him her 'love'.

But AnnaLynne McCord was focusing on friends instead of romance on Thursday, as she enjoyed a Mexican getaway with her gal pals.

It was the 90210 star's 28th birthday that day, but it certainly didn't look like she had been indulging while celebrating.

AnnaLynne showed off her slender figure in an olive green two-piece with white trim as she lounged by the pool.

The actress flashed her pert derriere thanks to the cheeky thong style bikini bottoms, and also left her flat stomach on display.

After helping her big sister Angel and pal Lily to lather up on suncream, AnnaLynne was seen topping up her tan while propped up on a sunlounger.

The trio were later spotted splashing around in the swimming pool to cool off, and then went wine tasting.

AnnaLynne posed for some silly selfies with her sister, who is also an actress, which she later posted to Instagram.

'Thanks for the pinch! @othermccordgirl #BigSis #Friend #Life (she pinched me on the way home from the hospital... She's still trying to convince me that "it was out of love,"' she captioned the collage of photos.

Meanwhile, AnnaLynne set tongues wagging when she fuelled rumours she has rekindled her romance with 45-year-old Dominic.

She posted a photo which showed her and the Prison Break star pressing their heads together as they posed with a birthday cake. 

 '#BirthdayDinner w/ my friend, my love and the one man on the entire planet who drives me absolutely mad,' she wrote alongside the snapshot.

AnnaLynne and Dominic split in late 2014 after over three years of dating.

The Dallas star recently told People of the breakup: 'It's horrible. Public breakups are horrible. It's the worst thing on earth. You have to see your man with another woman.

'It's very hard. But I believe suffering is a part of life, and if you take something from it, then you're in a good place.'

She added: 'I love Dominic. I'll always love him, and we'll always be in each other's lives.'
