"Sunday Snuggles," Lucy captioned the photo, which quickly garnered over 22,000 likes and scores of comments from her fans congratulating her on what appears to be a new relationship.

While Louis didn't share a snap of him and Lucy from their weekend together, he posted a picture of them together in November.
"Look who I found.. @lucymeck1," Louis captioned the picture. "She looks just as good in a dress as she does in a leotard #tumble."

Earlier this year Louis revealed that he's keen to start settling down.
"Trying to find someone that you really get on with and finding the time to get to know them and stuff has proven a bit of a challenge," he told Attitude magazine. "I've been single for nearly three years now and it’s getting to that point where I would like to find someone to settle down with.
"I've been on one or two dates with a few girls but I'm just waiting for that person that gives me butterflies. That’s what I’m waiting for.
"I'm not into the whole single thing and if I am going to get into another relationship I want it to be a good one – I'm getting old now, man! I'm 25 years-old, I need to start looking at wifeys, the potential mother of my children!"
