VIDEO : Big Brother"s Lateysha Grace "hires personal trainer after 21lbs weight gain causes embarrassing dress split"

Lateysha Grace is probably still red-faced after she split her dress while attempting to twerk for Rylan Clark-Neal on Big Brother 's Bit On The Side last night, but she's taking steps for it never to happen again.

The mortified star has reportedly gained 21lbs while living in the Big Brother house, and that's why her dress was so tight.

A source told The Sun Online: “She’s put on 21lbs in the house!! Gorging on the food and not doing any exercise.

“She’s already booked a load of personal training sessions – she’s so mortified and she hates the way she looks now she’s put on weight.”

Lateysha is not happy about the weight gain

Following her eviction, where the mum-of-one became the sixth person to get the boot from the house, she suffered a serious wardrobe malfunction that left everyone cringing as her pink thong was laid bare for the world to see.

Thankfully Lateysha didn't run off camera, instead bursting into hysterics with the amused Rylan.

An embarrassed Lateysha said: “Why is this happening to me?!”

Things went from bad to worse for recently evicted Big Brother contestant Lateysha Grace as her twerk demonstration on Big Brother's Bit on the Side ended with her flashing her knickers to the nation.

In Wednesday night's instalment of the Channel 5 show, the reality was kicked out by the actions of Jason Burrill after a shock twist eviction.

When Lateysha appeared on BBBOTS Rylan Clark-Neal spoke to her about her twerking in the house, but things ended hilariously bad for the former star of The Valleys.

When shaking her behind to the camera she managed to rip her dress and flash her pick knickers to viewers in the biggest fail the show has ever seen.

Rylan was forced to run to her aide and zip her denim number back up.

"Oh my god, that is what you call a twerk," shouted the recently evicted housemate, as Rylan fixed her dress.

As the audience laughed, she added: “Why is this happening to me?!”

Rylan later said it "made his day".

Lateysha later said: "I can't believe that just happened."

Lateysha became the latest housemate to be evicted.

Jason won £20,000 of the £100,000 prize fund in the annihilation week task which sealed Grace's fate.

Big Brother assembled everyone in front of podiums and said the first person to hit the buzzer after the button was activated would win the cash.

But Burrill's victory in the reality series came at a price - he had to select someone for eviction.

In a speech delivered to his housemates before Burrill uttered Grace's name, he apologised for the decision he had made.
