Allison Holker and Stephen "tWitch" Boss' baby-to-be has already made its TV debut ...or so Ellen DeGeneres led her audience to believe.  

After Dancing With the Stars pro Holker announced that she was pregnant on Monday, tWitch revealed on Wednesday's episode of The Ellen DeGeneres Show that they are expecting their first child together in March. Holker already has a 7-year-old daughter name Weslie Renae Fowler.

"March? Oh you're going to miss the Mother's Day Show. That's a shame. Y'all didn't plan that out right," Ellen joked.

While the host quipped that her co-worker should have made the announcement on her show, she did get a hold of the baby's first ultrasound. Well, sorta.

It was actually a photo of tWitch's face posted on a womb dancing to a heartbeat. "It's got your eyes and your hat," Ellen joked. "You got nervous for a minute, like I had your ultrasound."

ET caught up with Holker backstage at DWTS, and the mom-to-be was over the moon to finally be sharing her baby news.

"The hard part is keeping it secret for so long," she admitted. "We're so excited about this, we're so joyous. So to keep that locked inside, everyday I just wanted to tell the world."
