Actress Holly Marie Combs is set to wed after becoming engaged to boyfriend Mike.

The Charmed and Pretty Little Liars star announced her engagement on Instagram on Sunday (03Sep17).

"Yes. Just yes," she wrote alongside a picture of the new ring on her finger.

It is unclear how long the pair has been dating, but Combs began posting pictures with Mike on social media earlier this year (17), and in February she marked an anniversary with her fiance. However, she did not indicate how long they had been dating at the time.

"It was a happy anniversary with hims (sic)," she wrote.

This will be Combs' third marriage - her ex-husbands are actor Bryan Travis Smith and former Charmed key-grip David Donoho, the father of her three sons.
