Calvin Harris has apparently been keeping "in the loop" with Rita Ora's plans.
The Scottish DJ started dated British singer Rita in May 2013 but they broke up in June this year.
Both stars are in Las Vegas this weekend and Calvin, 30, is reportedly keen to stay on top of his ex's whereabouts in order to avoid any awkward run-ins.
“Calvin has been asking mutual friends to keep him in the loop of her plans so they avoid each other," a source told UK newspaper Daily Star.
“He’s been doing everything he can to avoid bumping into her.
"Calvin is in Vegas almost every week and feels like it's his turf. He doesn’t want the pressure of worrying about seeing her."
Rita, 23, seems to have wasted no time moving on and at the beginning of this month was linked to rapper Ricky Hil, the son of designer Tommy Hilfiger.
Her former flame is apparently keen to avoid a situation where he would have to see the pair together.
“If Calvin bumps into Rita and she’s with her new boyfriend, he’ll be gutted," the insider continued.
“He wants to know which parties and events Rita is planning on going to so he can stay well clear.
“Calvin knows that if they accidentally end up in the same place, it’ll be beyond awkward for the both of them.”
Calvin announced his split from Rita on Twitter at the beginning of last month. Since then he's been linked to singer Ellie Goulding, but both have rubbished the claims.
