"Heroes" star Ali Larter is engaged.

The blonde beauty and her long-term boyfriend, stand-up comedian Hayes MacArthur, are said to be "thrilled" after she accepted his marriage proposal.

A representative for Larter said, "It's true that Ali and Hayes got engaged over the weekend, and they're absolutely thrilled."

Neither of the pair has been married before, and no date has been set for the wedding.

Larter - who plays alter egos Nikki and Jessica in "Heroes" - recently gushed, "I told Hayes after three weeks that I wanted to marry him and that we could do it tomorrow. I look forward to the time that I'm at home with babies. He has brought light to my life. I feel lucky every morning when I wake up and see him."

"Not everybody is fortunate enough to find their soul mate in life."

Larter and Hayes starred together in comedy film "National Lampoon's Homo Erectus" earlier this year.
