Miranda Lambert and her boyfriend Anderson East put on a cute little show for fans during a recent Los Angeles concert. East was performing with Chris Stapleton during the latter’s show at The Greek when he asked Lambert if she would join him onstage to sing “My Girl.”

As fans cheered during the Wednesday night show, the “Little Red Wagon” singer took the microphone to perform backup with Stapleton’s wife as Anderson belted out the lead vocals to the classic song.

Lambert and Anderson’s impromptu duet of “My Girl” isn’t the first time the couple has performed a rendition of a lovey-dovey song. According to Entertainment Tonight, the pair dazzled a crowd during a Valentine’s Day show when they sang Mariah Carey’s “Always Be My Baby” together.

In February, East opened up about his and Lambert’s romance revealing to radio station 92.3 WCOL that they met when Lambert showed up to one of his concerts. “A friend of her introduced us,” he said. The 27-year-old singer wouldn’t reveal whether he and Lambert, 32, have ever written songs together since they started dating, but he did say that they like to “sit around and sing country songs.”

As previously reported, Lambert’s ex-husband, Blake Shelton, revealed earlier this month that he and his girlfriend Gwen Stefani co-wrote the song “Go Ahead and Break My Heart,” from his album “If I’m Honest.” In an interview with Entertainment Tonight he said the track was “very personal” for him and Stefani.

“You know, we obviously have this bond that is remarkable together,” he explained. “But the fact that we wrote a song together … I know that I don’t co-write that much because I’m very insecure about it I guess and [Gwen’s] kind of got her circle of people that she writes with. But for us to reach out to each other as writers, it may never happen again, who knows.”  

Lambert and East went public with their relationship in December, shortly after she divorced Shelton. The “Voice” judge and Stefani have been dating since November.
