The show is to kick off its seventh season Monday. Budig is replacing outgoing co-host Audra Lowe.
"I am excited for the opportunity to co-host a daily talk show, especially working with J.D.," Budig said in a statement. "I'm always looking to improve my life and the lives of those around me, and 'The Better Show' is the perfect example of a lifestyle show that does just that. It feels great to be a part of something that promotes better, positive living to viewers."
"We are very excited to have Rebecca join us and believe her addition will be a game changer for 'The Better Show,'" said Kieran Clarke, executive vice president and general manager of Meredith Video Studios. "She brings extensive television experience and has a fun, positive attitude that will connect with audiences."
Budig is known for her work on TV's "All My Children," "CSI," "Castle," "How I Met Your Mother" and "Hope & Faith." She also serves as host of HGTV's "Amazing Water Homes" and was the winner of ABC's "Skating with the Stars." She can currently be seen on the big screen opposite Ethan Hawke in "Getaway."
