Demi Lovato and Jennifer Lopez have a lot in common — way more than just being on Mariah Carey's "I don't know her" list. They have a deeper connection via Lovato's rumored new man, Brazilian MMA fighter Guilherme "Bomba" Vasconcelos.
Bomba and Lovato first met at the Unbreakable Performance Center in Los Angeles where they both train.
And this gym also linked Bomba to Lopez in a major way.
They even celebrate birthdays together — this squad is really tight.
Smart and Lopez hit up Bomba's birthday celebration in March 2016.
"Thanks for stopping by @beaucaspersmart @jlo #ysabel #birthday #LA #HOLLYWOOD #friends," Bomba wrote.
But the plot thickens — Smart is also friends with Lovato's ex Wilmer Valderrama!
And the two aren't just Hollywood acquaintances that give each other head nods at events...
They go to movies together.
"What's best after dinner? #DumbandDumber," Smart wrote under this photo of him, Valderrama, and another friend on Instagram.
