Pregnant Billi Mucklow wastes no time in hitting the gym post-holiday as she shows off her baby bump in tight workout gear

She's been sunning herself in Dubai for the last few weeks.

And not content with her constant beach workouts, pregnant Billi Mucklow made sure her first port of call after returning to Essex was her local gym.

The former TOWIE beauty - who is expecting her first child with her footballer fiancé Andy Carroll - posed for a picture mid-exercise session, resting on a giant inflatable ball.

Clad in black leggings and a sky blue vest top with her hair cascading over one shoulder, Billi looked far more glamorous than the average gym goer.

She tweeted: 'Gym Selfie Light work out on legs and arms before sweating it in out in my Hot Room #pregnancy #training #keepinginshape (sic)'.

Billi's workout plan didn't go down well with her fans, however, who anxiously pointed out that hot yoga wasn't advisable for pregnant women.

One user wrote: 'Anything that raises your body temperature is dangerous!... thought it was my duty as a midwife [to tell you]'.

'An increased internal body temp[erature] can stimulate the uterus to induce pre term labour', another concerned fan warned.

The 27-year-old star also shared another snap of herself standing upright, showing off her growing bump.

The star had a blast during her Dubai getaway, where she was joined by her mother and good friend Jenna-Louise, but was clearly missing her beau Andy.

She sent the West Ham striker a personal message as she cradled her bump on the beach, writing, 'Missing You @andytcarroll #babycarroll'.
