She welcomed her second child, the unconventionally named Wolf Nine, in November.

And Billi Mucklow was showing off her incredible post-baby body in a low-cut black swimsuit as she shared a number of snaps from her exotic getaway with her fiancé Andy Carroll, baby son Wolfie and his older brother Arlo, two.

The 29-year-old beauty displayed her impossibly toned legs and trim stomach in the simple one-piece, perching on the prow of a boat while sipping on a glass of wine.

The former TOWIE star has worked as a Bikram yoga instructor since leaving the reality show in 2013, so it perhaps comes as little surprise that she's in such great shape.

Her fans were quick to comment on how well she looked, with one enthusing, 'You look amazing Billi! I still don’t look like that after my first child!' and another commenting, 'Hot mumma'.

Another holiday snapshot saw Billi and West Ham United star Andy posing in their beach attire, each cuddling one of their sons.

The star captioned the adorable image: 'My Boys, My World #BigAc #LittleAc #Wolfie9 #TheCarrollBoys'.

'Wolfie Nine Carroll Your A Little Dream #SpecialTimes #AdventuresOfWolfie #MyBabyBoy', she wrote alongside another picture of her cuddling Wolfie.

Andy certainly looked to be making the most of his three-month break from football after undergoing surgery to repair a hairline fracture to his foot.

Billi had previously revealed that she and Andy were planning to wed in the summer of 2017.

Speaking to OK! magazine at the time, she said: 'I wanted to spend a few months enjoying Arlo as a baby before we started getting busy with wedding stuff.

'I definitely want a massive wedding, though.'

The couple announced their engagement in November 2014, after Andy had popped the question during a romantic mini-break in Rome, Italy.

And while their new addition is Andy's second child with Billi, Andy is also dad to daughter Emilie Rose, six, and son Lucas, four, from previous relationships.
