Caroline Flack and Andrew Brady have sparked rumours they have tied the knot.

The on-again-off-again couple first met in February this year, following his time on Celebrity Big Brother.  And while they have split twice since then - including calling off their engagement in July - things appear to be back on track for the pair. The couple are rumoured to have reconciled after Love Island ended this summer, and have seemingly been trying to keep their romance more quiet this time around. However, recent photos hinted that they may have taken another big step in their relationship. https://www.instagram.com/p/BiZ1FeVlAyr/?utm_source=ig_embed Photos obtained by The Sun show the couple walking their french bulldog, Ruby Coco, near Caroline's London flat. And while the Love Island host kept her hands in her coat pocket, Andrew was spotted with a gold band on the fourth finger of his left hand. Neither one of them have yet confirmed - or denied - the news.   The on-again-off-again couple announced their engagement in April, before jetting off on holidays to celebrate their happy news. https://www.instagram.com/p/Bjxem1Ll9Eg/?utm_source=ig_embed A source told The Sun at the time:

“Caroline is totally in love. Andrew treats her like a princess. “She’s grinning from ear to ear because she feels like she’s found The One. “All Caroline’s family love him and he’s got the Flack seal of approval."

The couple split again in July this year as Caroline flew out to begin filming Love Island, before appearing to reunite in August.
