The 'TOWIE' star took to Twitter on Wednesday night (29.08.18) to reveal she's been standing by her on-off boyfriend after he re-entered rehab.

Alongside a clip of them sharing a motorcycle ride, she tweeted: "Thank you for all the amazing comments & support for my show!

"The response has been overwhelming not to mention trending No1 on twitter! I love Arg very much, He is working so hard. We're back together & happy! #RideOrDie (sic)"

Her tweet comes after Arg shared a gushing message of his own showing how proud he is of his partner's new show 'Diva Espana'.

He wrote: "Can't desribe how proud I am of my girlfriend @missgemcollins #DivaEspana NUMBER 1 TRENDING on Twitter! Finally seeing the real her @ITVBe (sic)"

Earlier this week, Arg revealed he was back in rehab to get the "ongoing support" he needs.

The 30-year-old reality star - who also spent time in The Priory for alleged drink and drug issues in 2014 - spent three months in a facility in Thailand over the festive season in 2016 in a bid to curb his wild ways.

He said: "It's not been an easy time but I'm happy to be back in a programme that gives me the ongoing support I need.

"I'm thankful for the incredible support I have received from my family, close friends and colleagues."

It had been reported his issues had put a "huge strain" on his relationship with Gemma and caused them to split, but they are now in a better place.

However, Gemma has been supporting him throughout his struggles.

She said: "It was incredibly raw, yes, it's been an incredibly difficult summer. But, that said, you know, we're back now in Essex and Arg is receiving help and you know, as long as he's doing well, that's great for him and for us.

"I'm just supporting him on his journey and I'm feeling pleased that the viewers get to see what goes on behind the cameras and I think it's good for them to see that behind all the glamour there's real ups and downs, even in celebrities' lives."
