Tobi Pearce, fiancé of fitness queen Kayla Itsines, is reportedly facing jail time.

The fiancé of fitness entrepreneur and Instagram sensation Kayla Itsines has reportedly been charged with reckless driving and possession of prescription drugs.

Tobi Pearce, one-half of the Kayla Itsines fitness empire, was allegedly caught with four tablets of the drug Cabolin when he was stopped by police almost a year ago for allegedly driving recklessly, The Advertiser reports.

If found guilty, it is understood the 24-year-old faces a minimum 12-month driving ban and maximum of two years in prison.

Cabolin, a brand name for a drug more commonly referred to as cabergoline, is often used to help offset many of the side-effects of steroids.

Mamamia has reached out to Pearce and Itsines for comment.

Pearce is currently CEO of the pair’s business The Bikini Body Training Company.

This would not be their first experience with the court system. In March 2015, Pearce and 25-year-old Itsines took fellow fitness bloggers and former couple Leanne Ratcliffe (aka Freelee the Banana Girl) and Harley “Durianrider” Johnstone to court after asserting the duo published defamatory claims about them on their respective YouTube channels.

Itsines and Pearce alleged Ratcliffe and Johnstone wrongly claimed Itsines’ program starved people and that Pearce used steroids. Court documents accused Ratcliffe and Johnstone of being ‘foul-mouthed parasites‘ and the matter was settled out of court.

In October last year, the young Adelaide-based couple came in at number 51 on the BRW Young Rich List with a wealth of $46 million, the youngest debutants on the list.

The year before, Itsines, who has over 11 million Facebook followers and over 6 million Instagram followers, posted one of many tributes to her fiance, giving her fans a greater insight into one-half of the bikini body juggernaut.

In the Facebook post, Itsines addressed claims Tobi was “expelled from school” and asked why people “always think this is a bad thing”.

“Tobi was actually asked to leave school because he spent a lot of his time being bored and yes this made him be a little distracting to others. He’s a genius. I’m not saying that because I think he’s smart, he really is a genius with an AMAZING mind. He was studying classical piano at age four and was at university level by 13-years-old.”

Itsines went on to write her fiance has “a photographic memory”, can “fix anything” and will learn languages in “a few months”.

“He sometimes comes across as arrogant because he already knows what you are going to say, so he is quick to respond. But when you get to know him, he’s the best person you have ever met and can help you succeed or improve yourself in many ways. All you have to do is ask and listen,” she added.

Pearce will face a two-day Adelaide Magistrates Court trial in May this year over allegations he was recklessly driving in Adelaide in February last year, as well as the charges relating to the prescription drugs that are illegal to carry without medical permission.
