"Bachelor" couple Jason Mesnick and his wife Molly Mesnick have welcomed their first child together, a baby girl.

Jason, 36, announced the news on Twitter on Thursday evening.

"We welcomed the most beautiful healthy baby girl to our family today Riley Anne Mesnick," he said. "Thank you all for your well wishes! @MollyMesnick."

"Oooo this little peanut has already got me wrapped around her finger! #RileyMesnick," his wife added on her own Twitter page on Friday, March 15.

Jason also has a son, Ty, from a previous marriage. Molly has no other children. The two wed three years ago, on Feb. 27, 2010, in a televised ceremony and announced Molly's pregnancy in October.

"The Bachelor" / "The Bachelorette" - 4 televised weddings

The couple met on the 13th season of "The Bachelor." Molly was the runner-up. Jason, the main star, proposed to contestant Melissa Rycroft but he later broke up with her during the season finale and reunited with Molly during the episode. Rycroft wed Tye Strictland in December 2009 and welcomed her own first child, a daughter, in February 2011.

Jason and Molly became the second pair from the ABC dating reality show franchise to have their wedding televised, following season 1 "Bachelorette" Trista Rehn and contestant Ryan Sutter, whose wedding aired in December 2003. They are now parents to a son and daughter.

The third "Bachelor" franchise couple to tie the knot if a televised ceremony was "Bachelorette" star Ashley Hebert and winner J.P. Rosenbaum, who tied the knot on Dec. 1, 2012. Jason and Molly, as well as other former contestants of the franchise, attended the wedding.

The most recent "Bachelor" star, Sean Lowe, and winner Catherine Giudici are also set to wed on TV.
