It looks like Chyler Leigh has become real good friends with Melissa Benoist’s husband Blake Jenner since the actor appeared on “Supergirl” last season.

Jenner — who turned 24 on Saturday, Aug. 27 — got a one of a kind birthday greeting from Leigh, who plays Alex Danvers, his wife’s onscreen sister, on the CBS-turned-CW series.

“@Blake_Jenner Since I can't sing #HappyBirthday to you in person, I send this to celebrate ur special day (Hit Play),” the 34-year-old actress tweeted, along with a hilarious video of what appears to be a heavy metal version of the “Happy Birthday to You” song. Watch the crazy clip below.

Benoist, of course, didn’t forget to greet her man a happy birthday on social media. “Today is your birthday. It's your birthday today. I love you, you big goof @blakedaflake,” the 27-year-old actress captioned an Instagram pic of Jenner and their pet dog on Milli.

According to Us Weekly, Benoist and Jenner secretly tied the knot in March 2015 after filming for the “Supergirl” pilot wrapped. A source told the news outlet at the time that the wedding was “very small with their families there.”

Benoist and Jenner met on the set of “Glee,” where Benoist played singer Marley Rose and Jenner played fellow New Directions member Ryder Lynn. Though their characters only had one awkward date during the entire run of the FOX series, the real-life couple dated for a year before Us Weekly broke the news in July 2013 that they had already got engaged.

Jenner appeared as Cat Grant’s (Calista Flockhart) estranged son Adam Foster in two episodes of “Supergirl” Season 1. It’s unclear, however, whether Jenner will be reprising his role in Season 2, as Flockhart is no longer a series regular next installment.

“[But] she’s in the first two episodes and we’re talking to her about doing more,” executive producer Andrew Kreisberg told Collider of Flockhart. “It’s funny because, from our perspective, we thought she wouldn’t do any. And it’s not because she doesn’t love the show. She’s such a huge fan of the show, but moving to Vancouver, we assumed that we would part as friends. But she’s so into the show and feels such an allegiance and a responsibility to it that she’s agreed to come back, so we’re very happy.”

“Supergirl” Season 2 premieres on Monday, Oct. 10, at 8 p.m. on The CW.
