Frankie Muniz is engaged

“Malcolm in the Middle” is getting married? That's what we've heard.

Muniz, 25, tweeted that he's proposed to his girlfriend, publicist Elycia Marie Turnbow.

"After 4 years together, I'm so happy to be ENGAGED to the love of my life @ElyciaMarie!!!" Muniz posted Saturday.

Turnbow responded: "It's official.. I'm engaged!"

(And if Malcolm getting married doesn’t make you feel old, wait until you hear this: Jonathan Lipnicki, who played the bespectacled little boy on “Jerry Maguire," is now 21.)

Apparently Frankie and Elycia are in a better place than they were in February, when police were called to their Arizona home to investigate an allegedly physical spat between the two.

"Neither one is interested in finger-pointing at the other," Muniz's rep said at the time. "It was a situation that escalated beyond a point that it needed to be. If anything, they will look back at this as a learning opportunity."
