They've been dating for at least seven months and Gwen Stefani and Blake Shelton are clearly smitten with each other, as the Voice coach and country star celebrates a big personal milestone.

The 46-year-old pop and ska singer took to Twitter and Instagram Saturday to wish her beau a happy 40th birthday, complete with adorable throwback childhood pics of himself.

"Happy birthday to my favorite person I ever met @blakeshelton gx #superbabe," she tweeted.

"Now THIS is how you start your 40's!!!!!!!!" Shelton replied. "Thank you @gwenstefani for everything..."

Stefani retweeted him and also replied with kissy face emojis.

She also wrote on Instagram, "Happy birthday to @blakeshelton literally my favorite person gx."

The longtime Voice coach and his girlfriend, who has co-starred with him on the NBC show, stepped out as a couple in November, months after he filed for divorce from Miranda Lambert, 32, and Stefani filed her own papers to end her marriage to husband Gavin Rossdale, 50, father of their three sons. Lambert has since moved on with new beau Anderson East, 27.

Blake has often spent time with Stefani's family since they began dating. A few weeks ago, she and her and Rossdale's eldest son, Kingston Rossdale, 10, celebrated the boy's birthday with a fun day with his brothers and also took a helicopter ride with Shelton to the Indianapolis 500, where Blake headlined the annual Firestone Legends Day concert.

Stefani will celebrate her own birthday in October.
