Gwen Stefani, Blake Shelton Channel ‘Scooby-Doo’ For Her Son Apollo’s Birthday

Gwen Stefani stepped out in matching green and purple dress as Daphne for her son's Scooby-Doo birthday party last weekend.

The "Hollaback Girl" singer posted a few snaps of the themed party on her Instagram, showing off her bright red hair, green scarf, and purple fishnet stockings. Meanwhile, her youngest son, Apollo, wore a Scooby-Doo onesie to the event.

Stefani's boyfriend, People's 2017 Sexiest Man Alive Blake Shelton, traded his crisp suit and white shirt for a green button-down and a shaggy hair as the detective group's resident hippie, Shaggy.

Apollo, born Apollo Bowie Flynn Rossdale, is Stefani's son with her ex-husband, English musician Gavin Rossdale. Apollo will turn 4 on Wednesday, Feb. 28.

The 48-year-old has two other kids with Rossdale: Kingston (11) and Zuma (9). She divorced the "Love Remains The Same" singer in 2015.

She started dating her fellow The Voice U.S. coach shortly after but did not publicly reveal their romance until a few months after she announced her split with Rossdale.

Becoming A Family

Since 2015, Stefani and Shelton have been at the center of the rumor mill, with sources claiming that the celebrity couple is either getting hitched or trying to conceive a child (or both). A new report from Us Magazine says that the country singer is "devoted" to Stefani's three children from her previous marriage.

"Blake is extremely attentive, loving and doting towards Gwen and the boys," the unnamed source said.

His relationship with Stefani's children from her previous marriage apparently made the singers try to have a baby.

"Blake has always wanted children," the publication's source added. "And he's great with Gwen's kids, which prompted them wanting their own."

North America Tour

With the couple currently trekking North America as part of Shelton's Country Music Freaks Tour. In a recent performance at the Scottrade Center on Saturday night, Shelton brought Stefani onstage to perform a duet and the two shared a romantic moment in front of the adoring crowd.

A Twitter user who attended the concert was able to capture Shelton and Stefani's moment onstage.

"You see how much I love y'all?" Shelton said to the audience. "I hired Gwen Stefani to come out and sing, and it was very expensive."

They performed the song "Go Ahead and Break My Heart" from the album If I'm Honest.
