Jennifer Lopez has been criticized after she was spotted on a private jet this past weekend with former flame Ben Affleck.

Sources say the pair jetted off for a romantic getaway trip to a luxury ski resort in Montana, where the Hollywood A-Lister reportedly owns a chalet.

Ben, 48, and Jennifer, 51, looked more than comfortable in each other's company as they sat side-by-side in an SUV. Affleck was seen in the driver's seat, amid rumors he's been spending time at the singer's LA mansion.

In the pictures, Ben and Jennifer went for the casual look as they stood close together while exiting their private plane.

The pair - who have a net worth of over $300 million - had a considerable amount of luggage between them.

Argo actor and director Affleck is said to own a ski chalet at the Yellowstone Club in Big Sky, Montana  - where he's believed to have stayed with Lopez. He has taken family vacations there with ex-wife Jennifer Garner and their three children, Violet, 15, Seraphina, 12, and Samuel, 9.

Sources have told E! that the pair spent "about a week" together at the club and "were alone" during their stay. They arrived back in LA on Saturday - with Jennifer spending Mother's Day with her 12-year-old twins - Emme and Maximilian.

It is the second time Ben and Jennifer have been spotted together in just over a week.

The former celebrity couple were engaged in 2002. They postponed their 2003 wedding and officially split in 2004. They have been seen rekindling their romance following JLo's split with ex-fiancé Alex Rodriguez. Ben has been an active user on the celebrity dating app Raya.

But some social media commenters believed Jennifer - who has been married and engaged multiple times - cannot "stay single."

"This lady cannot stay single. Great example as a mother for her children especially her daughter to choose womanizers and alcoholics," a very very shady comment read.

"Man she must not be able to live without a man. It's called codependence," another person wrote.

"Obviously neither one of them can be alone. I'm and of itself, money and fame does not buy happiness," a third chimed in.

"The bedsheets not even cold yet & they're jumping towards what can only be described as a trainwreck waiting to happen," a fourth commented.

"Jesus she can't be without a man for more than a second! Girl, think about your kids," an angry fan added online.
