Ben Higgins, Lauren Bushnell of 'The Bachelor' celebrate engagement

PORTLAND, Ore., July 13 (UPI) -- Ben Higgins and Lauren Bushnell of The Bachelor celebrated their engagement over the weekend.

The Season 20 couple celebrated with family and friends Sunday in Bushnell's home state of Oregon, nearly four months after Higgins proposed on the finale.

Bushnell's sister, Mollie Bushnell, and brother, Brett Bushnell, were among the guests in attendance. Partygoers shared photos from the fête on social media, including a picture of Higgins and Bushnell with the dessert table.

Higgins competed for Kaitlyn Bristowe's affections on The Bachelorette Season 11 before starring on The Bachelor. He chose Bushnell over JoJo Fletcher and later explained his decision on the Today show.

"Early on in the whole process, Lauren had something that just really stood out to me," the star said. "I could not picture my life without this woman. That was never a doubt to me ... She belongs in my life forever."

"I want to marry Lauren quickly," he added. "But I would like to wait a while, get our family and friends involved, make sure it's something Lauren wants and that I want because we want this to be a celebration."
