Justin Time! Katie's Hot Newfox

It’s serious – he’s even met her daughter Suri

They’re two of Hollywood’s hottest stars and now it appears Katie Holmes and Justin Theroux are hotter than hot for each other!

In November last year, Woman’s Day reported that the unlikely twosome had fallen for each other after a secret four-hour tête-a-tête in a New York restaurant – and four months later they’re completely smitten.

“Things have certainly stepped up a notch or two,” the insider shares. “They’ve become extremely close and given they’re both lovers of their home city of New York, they’re enjoying sharing their favourite spots with one another. They’ve been sneaking around the city inconspicuously, which they could never do in Los Angeles.
