The actor Gavin Casalegno does not seem to be in a relationship with anyone before dating Larsen Thompson. There are no mentions whatsoever of his past relationship.
So, apparently, Larson is his first and only love interest. The two are very happy with each other and occasionally go out on adventures together. The Instagram of both the love birds has many photos of each other performing fun stuff.
Moreover, both of them being in the show business, they are also seen on red carpets and events together. Dressing beautifully, the couple looks so perfect with each other.
Gavin has acted in many television series and can be seen in several advertisements and has endorsed many products. He is on Instagram as @gavincasalegno, and Larsen is on Instagram as @larsenthompson.
