Instagram: Cristiano Ronaldo Overtakes Selena Gomez...

She's been taking a break from social media while she seeks treatment for mental health issues.

And while she's been gone, Selena Gomez's absence appears to have contributed to the actress and singer losing the title of most followed person on Instagram.

The new holder of the title is soccer star Cristiano Ronaldo, who, according to USWeekly Monday, has 144,338,650 followers compared to Selena's 144,321,029.
