May 10 (UPI) -- Professional dancers Allison Holker and Stephen "tWitch" Boss are expecting their second child together.
tWitch, who has served as a DJ on the show since 2014, surprised host Ellen DeGeneres and the audience by bringing out Holker during the Mother's Day-themed episode.
"Being that it is Mother's Day, we thought this was the perfect opportunity to announce that we're having a baby," Holker said.
"We're excited," tWitch added, saying they don't know the baby's sex just yet.
Holker and tWitch are already parents to 3-year-old son Maddox Laurel. Holker is also mom to 10-year-old daughter Weslie Renae from a previous relationship.
"Maddox kind of has no idea what's about to hit him but Weslie's so excited," tWitch shared.
"Weslie had a great reaction. When we told her she had tears coming down her face," Holker said. "She loves being a big sister, so we're really excited about that."
"Shuffle into DISNEYWORLD like a BOSS! @sir_twitch_alot @weslierboss @maddoxlboss @waltdisneyworld #disney #love #family #dance a family that dance together stay together shuffle," she wrote.
