Although it is unclear whether or not Doute's sister's wedding will play any part in the upcoming season of Vanderpump Rules, Doute own relationship drama is sure to continue. Throughout seasons 1 and 2, Doute was in a relationship with Tom Sandoval. When that relationship ended, Doute began dating James Kennedy, and the pair is still together today.

In February, when asked if she would come back to the show by E! News, Doute explained, "I would. At this point, we're three years in and everything that I've been through, I put my life on the line for everyone to see. I'd want to continue the journey. I don't want to throw everything away just because I don't work at SUR. If there's a fourth season, I hope they'll ask me back."

In addition to her sister's engagement announcement, Doute also spoke of her plans for a "vintage inspired" wedding.
