Only a few weeks after news broke that Courteney Cox called off her engagement to Johnny McDaid, the actress was spotted out on what appeared to be a dinner date.

Cox was seen with Amy Poehler's ex-husband, Will Arnett, at the Palm Restaurant in Beverly Hills, California, on Tuesday night. A source tells ET that the two were "all over each other."  ET has reached out to representatives for Cox and Arnett for comment.

"It was just the two of them together," says the source. "They tried sneaking out and the manager helped them leave separately."

However, despite their private dinner, a source close to Cox tells ET they’re just friends.

Cox, 51, reportedly called it quits with her 39-year-old rocker fiance before Thanksgiving. The two got together in 2013 and announced their engagement in June 2014.

Earlier this month, there were rumors that Cox -- who was previously married to her Scream co-star David Arquette -- was dating her former Friends co-star Matthew Perry. A source close to the actors confirmed to ET that this report was "untrue."

Arnett split from Poehler in 2012 after nine years of marriage. The 45-year-old Arrested Development star was recently dating Arielle Vandenberg, 28. The two broke up in June after only six months.

In 2013, Arnett opened up to Detailsabout his divorce. "All people have been doing since the dawn of time is trying to figure out how to live this life and be happy," he said. "I'm no different."
