It's party time for "Bachelor" alum Ben Higgins and his fiancée, Lauren Bushnell.
The reality TV lovebirds have been celebrating their upcoming nuptials with joint bachelor and bachelorette festivities in Las Vegas.
The couple, who got engaged in Jamaica during "The Bachelor" season 20 finale, are toasting their future together in a series of fun fêtes featuring plenty of friends and co-stars — several of whom shared pics on Instagram.
On Thursday, Higgins, 28, and Bushnell, 25, invited pals to a sunny poolside party.
Guests included "Bachelor In Paradise" stars Ashley Iaconetti, Jared Haibon, Tanner Tolbert, JJ Lane, twin sisters Haley and Emily Ferguson, and Amanda Stanton.
In the evening, the happy couple took his and her limos to two different locations to keep the Sin City celebration going.
Back in March, Higgins told TODAY's Hoda Kotb and Jenna Bush Hager that he wanted to "marry Lauren quickly," but so far the couple have yet to set a wedding date.
As fans know, the engaged duo will appear together in their own spinoff reality program, "Ben & Lauren: Happily Ever After?," an unscripted series that will follow the couple as they plan their wedding and their life together.
The show premieres Oct. 11 on Freeform, formerly ABC's Family channel.
