The 30-year-old TV personality revealed she said "yes" to her boyfriend Kevin Manno on Wednesday.
"Yesterday was the most special, magical day of our lives -- so far!" Ali told ET in an exclusive statement. "The moment was beautiful. Just the two of us in our new home with our little dog Owen. We couldn't be happier!"
The former reality star also shared the happy news on her website, ailuvs.com. "So excited to share that Kevin asked me to be his wife and I said 'YES!!!' No actually, I screamed yes. Ha!" Ali wrote. "He proposed yesterday and we had the most beautiful, magical day with our closest friends and can't wait to celebrate with family back home."
"I can assure you that Kaitlyn is NOT the first person to have sex with someone on the show," Ali wrote on her blog. "Sure, Kaitlyn did it before the infamous fantasy suite, but does that really matter?"
