Just two months since giving birth, Katherine Heigl isn't ready to part ways from her newborn son Joshua for any length of time, the doting mom demonstrated when she made a Valentine's Day appearance at the Late Late Show.

The actress, who was promoting her new TV series, Doubt, was feeling the love as she brought both of her valentines, Joshua Jr. and her husband Josh Kelley, backstage with her and even reminisced to host James Corden about how she knew her now-hubby was crazy about her when they first started dating years ago.

The British comedian congratulated the mom-of-three on being married for nearly ten years before asking, "Is it true that John Mayer was involved in your courtship?"

Laughing, a pink-clad Heigl acknowledged that yes, the brooding musician unwittingly played a part in making the couple more serious.

The 38-year-old then admitted that a month into her new relationship with Kelley, she was seeking clarity about how serious her boyfriend was about her. Cue the mischievous plan.

"I had run into John, who was in town, making a record or something. We were just hanging out, having drinks, having dinners, as friends. He wasn't interested in me at all," she emphasized. "But Josh didn't know that."
