US gymnastics legend Simone Biles seems to have split from boyfriend Stacey Ervin Jr after reportedly discovering on February 14, Valentine's Day that he was cheating on her.

In the last few months, there has been very little social media communication between the couple, who would otherwise post messages about each other every second day. Biles, 23, has even unfollowed fellow gymnast Ervin, 25, on Instagram. The last time the four-time Olympic gold medal-winner Biles, Instagrammed a photograph to Ervin was on January 12 when the two were at Disney's Animal Kingdom.
