After splitting from Joshua, Tayshia began seeing model Chase Olswang, whom she dated up until filming began for The Bachelor in September 2018. According to Chase, he and Tayshia met at a bar in Newport Beach, CA, in November 2017 and went on to date for about 10 months. The two seemingly even went to the Bahamas together right before production began on season 23.
"We fell in love really quickly," the model told Us Weekly in February 2019. "I moved some things around . . . before she ended up deciding to leave [for The Bachelor], because she still wasn't really sure if she was going to go on the show or not. She was still back and forth . . . she wasn't sure. As it got closer, I could kind of see changes between us and I could kind of tell that she was leaning toward going. I don't know all of the exact reasons for that." Chase added that they were still in contact after filming wrapped but probably wouldn't be rekindling their romance.
