Nicole's shock discovery: It's been going on for months!

Even a phone call from her love rival wasn’t enough to set Nicole’s mind at ease.

Nicole Kidman has been torturing herself by poring over flirty TV scenes between her husband and Jennifer Lopez. And what’s making matters even worse is the knowledge this footage was shot months ago.

It’s become clear the close bond between Keith Urban, 46, and J-Lo, 44, which was first revealed in scandalous photos published across the world last week, has been a slow burn.

As Woman’s Day reported at the time, Nicole – who’s currently filming Queen Of The Desert in Morocco with her and Keith’s two daughters, Sunday, 5, and Faith, 3, by her side – furiously put word out among her and J-Lo’s mutual friends to demand that the Latina pop star keep her hands off her husband while they’re working together on American Idol.

We understand Nicole’s reaction to the photos, in which Keith and J-Lo are seen giggling and touching, has left Jen “absolutely mortified”. Friends tell us that as far as she’s concerned, she and Keith were “just having fun together” – but she does concede “others might see it differently”.
