Josh Altman, co-star of Bravo’s Million Dollar Listing L.A. has proposed to his longtime girlfriend, Heather Bilyeu, who’s also featured on the show.

They got engaged in June and have only recently revealed the exciting news, ahead of the show’s premiere on Wednesday.

Bilyeu took to Instagram to write, “I'm very excited to announce that I am now engaged to my best friend @thejoshaltman. Thank you for making me the luckiest & happiest woman baby! #love #bliss #hapiness #realestatecouple #mdlla.”

She also tweeted to Bravo:

Altman surprised his now-fiance by taking her to what he told her was just an ordinary listing. While there, he got down on one knee to propose. "I had absolutely no idea. He planned it perfectly. He did not let on whatsoever that there was something out of the usual going on,” she said, MSN reports.

On Tuesday, Altman told Bravo’s TV Dish "It was just the right moment. I love her more than anything in the world. She's my best friend. There's nobody I'd rather spend the rest of my life with than her."

He also took to Instagram to write, “Couldn't be happier. One of the most exciting moments of my life! @heatherbilyeu #bravo #mdlla.”
