Former The Bachelor star Charlie O'Connell is an engaged man.

Charlie -- who starred on Season 7 of The Bachelor in 2005 -- proposed marriage to his girlfriend, 31-year-old Playboy Playmate Anna Sophia Berglund, and she accepted.

Once the couple got engaged, Charlie, 42, changed his bio on Twitter to read, "Engaged 2 my #soulmate @annasophiab." And Anna edited her bio to say, "Actress Model Playmate Realtor Dog Mom Engaged."

Actor Jerry O'Connell talked to People about his little brother Charlie's big engagement news.

"It's exciting!" Jerry said. "We're going to do the wedding this spring. I'm the best man -- we're all super stoked. It's great. She's a beautiful girl, she's so nice. I can't wait for him to join the married club."

Anna has documented sweet moments for the couple on her Instagram account. In recent months, she and Charlie have done a lot of traveling together with stops in romantic destinations such as Paris, Portugal, Greece, and Singapore.

In one picture, the bride-to-be and her future groom locked lips at a cozy restaurant with an enormous pool in the background. Charlie and Anna also walked the red carpet together at the premiere for Living Among Us on February 1.

As fans may recall, Charlie did not end up proposing to his season's finalist, Sarah Brice, when he looked for love on The Bachelor over a decade ago.

Instead of a diamond ring, Charlie gave Sarah his final rose as well as a less-significant promise ring during the finale. The pair then dated on and off for five years.

Charlie and Sarah first split in 2007, but they resumed their romance the following year, when Sarah admitted the breakup had been due to Charlie's excessive drinking and her desire to be more independent.

The couple eventually called it quits for good on their relationship in 2010.
