LeAnn Rimes is worried that Eddie Cibrian might cheat on her.
And Jennifer Lopez can sort of relate.
The singer opens up in the latest issue of People and initially praises boyfriend Casper Smart for helping her "heal" from her latest divorce.
But she also expresses concern over the couple's 18-year age difference, telling the magazine:
"I ask him, 'Why don't you go find a young girlfriend and get out of here? What do you want with me?' And you think, 'How long is this gone be?' You think, 'Okay, in 10 years I'm going to be like this and you're going to be like that...'
Forget 10 years from now, though. Have you seen these Jennifer Lopez bikini photos? Could Casper really do better?
And is Lopez content with the relationship? It certainly sounds that way:
"The truth is we don't know what's going to happen. We're loving this moment right now. We make each other happy."
