Gwen Stefani cuddled up to one of the main men in her life on Thanksgiving -- her 9-year-old son, Kingston.

The mom of three shared an adorable snap of herself planting a kiss on her oldest child, who she shares with her ex-husband, Gavin Rossdale.

“#happythanksgiving #soblessed #grateful,” she tweeted on Thursday.

The 46-year-old singer spent the day with her brood at her mother's house in Southern California, but her new love interest, fellow Voice judge Blake Shelton, wasn't with her.

Shelton did, however, also take to Twitter to share a Thanksgiving message, though his was rather NSFW compared to Stefani's note.

"Happy thanksgiving everybody!!!!" he wrote. "And to any haters out there, have yourselves a nice warm slice of I don't give a s**t..."

Earlier this week, Stefani told ET that she loved her country crooner beau -- sort of.

While her Voice co-star Adam Levine was talking about Blake during a live taping on Nov. 23, Stefani couldn’t help but butt in.

"F**k Blake. I've known Blake for too long. Blake's just my buddy," Adam joked with ET. "I'm just kidding. I love you, Blake! Kinda. Ish."

Without missing a beat, Stefani leaned into the mic, saying, "I love you too, Blake. Ish."

The budding romance just might be the distraction the No Doubt frontwoman needs while going through her divorce from Rossdale, which the two announced in August.

"I wish it didn't happen. I wish this that all this wasn't happening," Stefani explained in an interview with Ryan Seacrest earlier this month. "But at the same time, I feel like it was part of my life journey."
