Katharine McPhee and David Foster Are Dating, But Keeping It 'Casual'

Katharine McPhee and David Foster are, in fact, dating — just not exclusively.

A source close to the pair tells The Blast that the two started out with just a working relationship, but have since moved on to a romantic one.

The two were photographed Sunday night at an ATM in Brentwood, where McPhee planted her hand on Foster's backside as he took out some cash.

However, we're told McPhee and Foster are just keeping things casual.

McPhee and Foster have known each other for some time and they are also making sweet music in the studio together while McPhee focuses on jazz at the moment.
