Newly separated Ashton Kutcher doesn't have Demi to keep him warm this winter!

The Two and a Half Men star shared a lonely Twitpic of himself with an outdoor X-mas tree late Monday evening, where he's enjoying a Roman Holiday with a few friends.

The actor Tweeted the caption, "Keeping warm this holiday season, hope everyone is having a good one."

Meanwhile it seems soon-to-be ex-wife Demi, who still goes by @mrskutcher on Twitter, continues to foot the bill for Kutcher’s tanning expenses!

Apparently Ashton frequents Le Beach Club Tanning Resorts in LA, where Demi has an account, and he still pops in to tan on his ex's dime. “Ashton came in to tan and used Demi’s account,” a source told Star. “He just assumed his tan could still be charged to Demi. He didn’t offer to pay or anything. He didn’t say his name or anything either; he just walked in and assumed everything would go as usual.”

Good to hear the exes are still on friendly terms!
