The Season 19 winner of The Bachelor accepted a marriage proposal from her boyfriend of less than a year, Ricky Angel.
"Whitney Angel has a nice ring to it, yall!" Bischoff, 31, captioned a black-and-white photo of the couple on Instagram Friday which featured her smiling ear to ear and showing off her engagement ring.
Bischoff, an infertility nurse, toldUs Weekly in October 2015 she was "just casually dating."
"I don't know that I have a specific person that I'm looking for," she added. "I think that in general it's someone who makes me a better person, makes me happy, makes me laugh, and shares a common interest, so I don't know if there's a big stereotype with that."
Angel is a Chicago native who works as a regional sales manager at PMMI Media Group. He graduated from Illinois Wesleyan University in 2008, where he played varsity baseball. And since then, he has worked in sales and risk management.
Bischoff was previously engaged to former The Bachelor star Chris Soules, 34. While they appeared happy and in love after the show, the couple split in May 2015, only two months after the finale aired on ABC.
"Whitney Bischoff and Chris Soules have mutually and amicably decided to end their engagement," the couple told Us in a joint statement at the time.
"They part with nothing but respect and admiration for one another and will continue to be supportive friends. They wish to thank everyone who has supported them through this journey."
Rumors flew about what went wrong after the pair broke up. Soules was accused of getting a big head due to fame and blowing off Bischoff for his career and stint on Dancing with the Stars. Meanwhile, sources also claimed Bischoff was jealous of the Iowa farmer's DWTS pro partner Witney Carson. Bischoff also never moved to Arlington although that seemed to be their plan once filming ended.
The couple, however, insists they've remained cordial since calling it quits on their engagement.
Soules, who is currently single and still living in Arlington, told Reality TV World in late May, "We don't talk every day, but I still care about her, and we stay in touch. I wish her well occasionally and she's somebody who will always be in my thoughts and prayers."
He added, "There was a time for a while when I was not really even ready to think about dating. What we went through, of being engaged, you have to sort of let things heal and get back to [normal]."

But Soules is "absolutely" ready to date again and said his "heart is in the position to want to meet that person."
