\"Had the BEST girl catch up yesterday and got to meet baby Tristan,\" Stause shared on Instagram of the trio's outing. \"Heart melted!\"

Fitzgerald echoed that sentiment on Instagram, gushing that she \"finally met adorable baby Tristan.\"

Last month, El Moussa announced that she and husband Tarek El Moussa had welcomed their first child together on Jan. 31.

The couple married in October 2021 and recently saw their new show, \"The Flipping El Moussas,\" premiere on HGTV.

\"Selling Sunset,\" which premiered in 2019, has aired five seasons on Netflix to date and has been renewed through season 7.
