Since Selena split from The Weeknd, she has been spotted in the company of Justin several times.

The couple, who previously dated on and off from 2011 - 2014 and split amidst a cheating scandal, have been seen enjoying brekkie, going to church and even been on a rather romantic looking bike ride through Los Angeles.

Selena has also been to watch her first love play ice hockey, where she was snapped wearing his jersey. Aww.

Naturally, #Jelena fans are delighted by their recent frolicking.

This super cute video does seem to cement the fact they're once again an item.
