Justin Timberlake and Jessica Biel were skiing in Montana on Jan. 24 – but it looked like their marriage was heading downhill just as fast! 

The superstar couple acted more like strangers while dining in Big Sky Country, a witness revealed to The National ENQUIRER.

“There seemed to be some tension between them,” the Montana spy reported.

“They were not talking at all – Justin was on his phone the entire time, looking down.”

Jessica, 32, is six months pregnant with her first child with Justin, 34, but they weren’t acting like expectant parents.

Could the pair’s current cold condition be related to a hot summer night in Paris?

The ENQUIRER published photos showing Justin canoodling with one of his female backup singers at Paris’ VIP Room on Aug. 21.

“In Montana, things seemed to be chillier than the weather between Justin and Jessica!” added the source.
