It was then claimed the pair had parted ways three months later, although without any animosity.
A source told The Sun at the time: ‘She really fell for Graham… so when they decided to end things recently, it hit her very hard.
‘There is no animosity and Graham is still there for her, but she feels quite lonely at the moment.’
Yet, the blonde appeared to hit back at split claims just one day after they emerged, by sharing a playful selfie of the pair to Instagram.
She wrote defiantly in the caption: ‘4 days till I see my man @grahamnation can’t f**king wait!’
Leading lady: Sheridan recently returned to the spotlight, after taking a break to battle her mental health issues follow the death of her father Colin from cancer
However, the pair have not been seen together since November, and Sheridan was spotted cosying up to mystery man during her festive trip to Mexico.
Sheridan embarked on the girly holiday to end a drama-filled year – having taken a hiatus from acting and the limelight after struggling with her mental health.
Sheridan pulled out of West End production Funny Girl in 2016, following the devastating death of her father Colin from cancer, but returned to screens on Christmas Eve in the TV adaptation of David Walliams’ book Ratburger.
Speaking on the Jonathan Ross show of the tough time, she recalled: ‘I hate it and I always think “The show must go on” and I hate letting anyone down but I think the public understood in a way that you can’t choose when these things happen.
‘It was a gradual build up when my dad got diagnosed and I just couldn’t continue, I lost my mind, I completely did to the point where people were stopping me in the street and cuddling me because people understand that, it’s just life.’
