He's old enough to be her dad!

David Foster and Katharine McPhee were spotted getting cozy on a dinner date at Nobu Malibu over the weekend, E! News reports. The 67-year-old record producer and the 33-year-old American Idol alum sat at a table in the corner for privacy and engaged in some serious PDA.

"David and Katharine were very intimate during their dinner. David was seen grabbing Katharine's face and kissing her cheek several times. Katharine was doing the same to David's face and they were acting as if they were a couple. By the end of the date, Katharine, 33, sat on David's side of the table and cuddled the 67-year-old with a blanket," a source dished to the outlet.

The two have been friends for years, but it appears their friendship has blossomed into romance. Foster divorced Real Housewives of Beverly Hills star Yolanda Hadid in 2016, and the singer divorced her husband Nick Cokas in 2014.

Foster was recently linked to supermodel Christie Brinkley as well, so maybe he's just playing the field? We'll have to wait and see if this turns into a real relationship!
