The "Cool For the Summer" singer attended the UFC 199 match in Inglewood, California, on Saturday night, where she appeared to be in good spirits for most of the night as she watched the showdown ringside with her mother, Dianna De La Garza, and a friend.
"After almost six loving and wonderful years together, we have decided to end our relationship," their statement read. "This was an incredibly difficult decision for both of us, but we have realized more than anything that we are better as best friends. We will always be supportive of one another. Thank you to everyone who has offered us kindness and support over the years."
