A big reason to give thanks. Gwen Stefani and Blake Shelton shared a sweet kiss in a pic the No Doubt singer posted on Instagram on Thursday, November 24, as the pair spent Thanksgiving together with their families in Oklahoma.

"Happy thanksgiving," Stefani, 47, captioned the photo, which shows someone pointing at the couple's lips as they smooch. "We love u sooooooo grateful !!!!"

The pair, who as Us Weekly exclusively reported began dating at the end of last year, spent the holiday with their blended family, including the country superstar's mom, Dorothy (who was featured in another of Stefani's pics), as well as the "Make Me Like You" singer's parents and her three sons — Kingston, 10, Zuma, 8, and Apollo, 2 — with ex-husband Gavin Rossdale.

Stefani also posted a series of Snapchat pics and videos from the family celebration, including a turkey showdown between Shelton's bird and one prepared by her father, Dennis Stefani, and a video showing the "Came Here to Forget" singer, 40, singing along to Simple Minds' "Don't You (Forget About Me)."

On Friday, November 25, the group took to the skies for a helicopter ride, and Stefani shared pics of herself and son Apollo dressed in camouflage gear.

As Us Weekly reported earlier this month, the smitten couple, who met on NBC's The Voice, are "starting to finalize" their wedding arrangements, according to a source, and have already "met with vendors."

While they have yet to confirm their engagement, a second pal told Us that they hope to marry "before the end of the year."
