Holmes' boyfriend Pete Malleo popped the question in New York City and both individuals shared the big news on Instagram Thursday by posting the same cute photo of themselves and a gorgeous city skyline in the background.
"I said 'yes,'" Holmes captioned the image. "Thank you for such an amazing day @c3peteo... I'm so excited for this next chapter of our lives."
Malleo wrote on his own account, "Today I asked my best friend to marry me and she said 'yes' @ashleenicholexx."
Laurita, 45, gave the happy couple her best wishes on Twitter.
"Say congratulations to my daughter @ashleeholmes & her fiance @c3pete0," Laurita tweeted. "We are thrilled to announce their engagement!"
"I'm baaaaack! I can't get enough of my Bravo family!" Laurita, who made guest appearances last season, said in a statement. "Sometimes a little break is all I need to jump back in and bring my best! Looking forward to new beginnings. XOXO."
