Well that was one of the shortest break-ups, even by Hollywood standards…

Lili Reinhart and her Riverdale co-star Cole Sprouse are reportedly back together, following a very short break from their relationship.

The Betty Cooper and Jughead Jones actors had dated for two years, before calling it quits back in July.

So how do we know that they are back on? Because Lili Reinhart just referred to Cole Sprouse as her boyfriend during an interview about this year’s Halloween costume. No big deal…

“I think I’m leaning in towards a character for Halloween. I think I’m going to do it with my boyfriend, Cole,” the 22-year-old actress said in the interview with Coveteur.

“I don’t want to spoil it if it’s not going to happen, but it’s a TV duo.”

Not only are we relieved that our favourite on-screen and off-screen couple are back together, but we are beyond excited to find out what their joint Halloween costumes will be!

Any ideas?
