Mary-Louise Parker has finally found happiness with actor Jeffrey Dean Morgan — and has an engagement ring to prove it! A friend confirms to In Touch that the actress, 43, and Jeffrey, 41, are definitely set to wed, adding, “Mary-Louise is the nicest person and the best mother. She is really happy about this.” Jeffrey may have the right woman picked out, but the ring he bought was all wrong. “It was four sizes too big,” the friend reveals to In Touch, because the P.S. I Love You star forgot his fiancée’s ring size. When the pair weds, he’ll inherit a family — Mary-Louise has two kids: Will, 4, and Ash, a baby girl adopted from Africa in September. Jeffrey plays Mary-Louise’s deceased husband on Showtime’s Weeds.
