While it’s no secret that Cole Sprouse is a twin (hi Dylan) we had no idea that his Riverdale co-star and rumoured girlfriend Lili Reinhart might be one too?!

Cole took to his Insta stories recently to share a throwback snap of him and his brother along with a mysterious female friend, who looks uncanningly like Betty Cooper herself.

Them going way back would certainly make sense as towhy they’re so close now, what with Skeet Ulrich (Archie’s dad) having previously said: “You just hear them talking to each other like they've been best friends for 20 years.”

Alas the girl in the pic isn’t actually Lili, with the real person having come forward as Anna-Laura who simply bagged a pic with the twins on the set of a movie once.

But we’re still going to go ahead and believe in the theory of Cole and Lili having known each other in a past life, or at least having crossed paths when they were babies, because they’re just too in sync to not have.
