She then posted a sweet snap of Fury carrying little Bambi, adding: "Me and the girly been struck down with flu [crying emoji].

It comes after the couple recently found themselves at the centre of split rumours when Hague was spotted without her huge diamond engagement ring.
This followed Fury being filmed partying in Abu Dhabi surrounded by women.
According to reports, Paris Fury, the wife of Fury's older brother Tyson Fury, reached out to Hague to offer some advice to her following the incident having experienced similar in her own relationship.
A source said: "Paris and Molly have become very close, and Molly often goes to her for advice. Paris has been through similar things with Tyson, so she understands what Molly is going through and she’s a great support for her."
Speaking to OK! Magazine, they added: "She’s told Molly she needs to pull the reins in and put her foot down with Tommy. Paris is a very strong woman and Tyson wouldn’t be who he is today without her."
