Boss, who works as DJ on the Ellen show under the moniker 'tWitch,' donned a brown derby hat with a white polo shirt and slacks for the joyous summer gathering.

'Can't even express all the incredible emotions we are feeling right now!' the Minnesota native, 31, who is seven months pregnant, wrote in the caption. 'I am so excited to be bringing in another beautiful baby girl into the world.

'And we are so grateful for all the LOVE that we were showered with yesterday from our friends and family joining us in the gender reveal! This baby girl is already surrounded by love and support! Here we go @sir_twitch_alot.' 

Holker and Boss, who met in 2010 filming So You Think You Can Dance and tied the knot in 2013, are parents to three-year-old son Maddox Laurel, and she has a daughter named Weslie Renae from a previous relationship.

Holker told the studio audience, 'We thought this was the perfect opportunity to announce that we're having a baby!'

Ellen told Boss, 'Congratulations! How long have you known and kept this from me?'

He replied, 'It's been a while Ellen, it's been a little while - but you know, we gotta keep it under wraps for a second.'

Holker, speaking with the magazine Fit Pregnancy And Baby in 2016, opened up about how she was the very first dancer on the ABC staple to dance while expecting.

'There I was in these itty-bitty costumes, flaunting myself, at four-and-a-half months pregnant,' she said. 'If you’ve ever been pregnant, you know that even in those first few weeks, you have to make frequent trips to the restroom. 

'Well, I had to go what felt like 20 times during a show, and I needed three people to help me peel the outfit on and off each time. I couldn’t do it myself!'
