Jacqueline Jossa has returned to Instagram for the first time since it was reported she confronted her estranged husband Dan Osborne over his alleged holiday romance with Brazilian bikini model Etila Santiago.

The EastEnders actress, 33, split from the TOWIE star, 34, with whom she shares daughters Ella, 11, and Mia, seven, in March following a nine-year marriage, which was plagued with accusations of infidelity levelled at Dan.

On Tuesday, Jacqueline uploaded a promotional video of herself giving her hair a glow-up and while she didn't directly address her ex, she made a subtle but pointed comment about 'feeling like me again' amid her marital woes.

Jacqueline is said to have been left upset by the romance amid Dan's trip to Miami, which dashed her hopes of saving their marriage. 

However, she appeared to put on a brave face in her latest social media post, in which she was joined by daughter Mia, where she told of her need to give her hair a boost after it was left 'in bits' following a 5k run in the hot weather.

Jacqueline, who went make-up free in the video, told her fans how she needed 'to feel like me again' as she showed off the various hair care products she planned to use in the clip.

After transforming her brunette locks with Give Me products and putting on make-up, Jacqueline looked amazing as she beamed to the camera.

Remarking on her transformation, Jacqueline shared: 'I feel so much better now, I'm all fresh and ready to go out. Isn't it crazy what a little bit of me time can do?'.

Captioning her post, while perhaps subtly alluding to needing a boost amid her marriage troubles, Jacqueline added: 'Well I definitely needed that!... Feeling like me again.'

Jacqueline's post comes following her 'confrontation' with Dan which came after she was tipped off by eagle-eyed pals who spotted Dan and Etila sharing similar sunset snaps to Instagram amid his recent trip to Miami.

A source said: 'Dan started chatting to Etila on Instagram before his trip to Miami as he saw they both had a passion for fitness. They met up a few times during his trip and really hit it off, spending a lot of time together hanging out and chatting. 

'However, Jac's mates notified her about Dan's movements having suspected who he was with online. So when he was back in the UK, she asked him about it.'

They told The Sun: 'It's obviously very sensitive as they are co-parenting, but Dan is a single man now. Jac is upset as she still feels there's a chance her and Dan could rekindle.'

Etila is a bikini and fitness model who regularly shared snaps of her incredible figure online. Her Instagram profile reads: 'I help women build lean, athletic bodies with elite-level coaching.'

The Daily Mail has contacted Dan, Jacqueline and Etila's representatives for comment.  

Following their split it was understood Jacqueline was unable to move past his past dalliances during their relationship and he could no longer cope with her 'behaviour'. 

The Daily Mail revealed that the ending came months ago with a quiet admission from Dan that, after years of trying to repair the damage caused by his past, he simply 'couldn't do it anymore'.

While they are yet to address their breakup publicly, both Jacqueline and Dan have been seen without their wedding rings in recent weeks.

Dan was pictured crying in his car in March, appearing to be overcome with emotion following the end of his relationship.

Sources close to the situation claimed to the Daily Mail that while the reality star has admitted wrongdoing in the past, he is now a different man and had turned over a new leaf following his party-boy ways in his twenties.

They added that Dan's family means the world to him and the father-of-three is understandably struggling with the strain of the situation.
