Jason posted a video of the special moment where he thanked everyone for attending.
‘We want to thank all of you guys for being here, though, seriously,’ the 30-year-old said.
Ashley then stuck a pin into a giant black ballon in the middle of their kitchen. As the balloon popped, numerous small pink balloons flew out, revealing the pair are having a daughter.
This new announcement comes after the couple revealed they were expecting in late February.
‘We are so overjoyed and excited for this baby!’ the couple spilled to Entertainment Tonight. ‘We absolutely LOVE kids and are so happy to finally be starting a family of our own.’
Jason dated Lauren Conrad for a few years during her tenure on The Hills with the couple finally calling it quits in 2006 due to Jason's issues with substance abuse. Lauren is now happily married to entertainment lawyer William Tell. The couple announced on New Year's Day this year that they too were expecting a baby this year.
