The actress hooked up with Beh last summer (10) just after breaking up with former boyfriend Jamie Kennedy, but a representative has confirmed the couple split a while ago.
A source tells Us Weekly magazine Hewitt is "doing well" after her latest heartbreak.
She was still very much in love on St. Valentine's Day in February (11), telling the publication Beh sends her flowers daily.
She said, "Every single day - I'm serious! He'll either give me a bouquet, or handpick one. So sweet!"
