Wedding bells for a very funny two-some.

Love and marriage is alive in TV land. "It's Always Sunny in Philadelphia" co-stars Kaitlin Olson and Rob McElhenney have tied the knot.

OK! magazine reports that the couple enjoyed an "intimate" wedding in Malibu after two years of dating. McElhenney created, exec produces and stars on the irreverent FX sitcom as "Mac," while Olson plays "Sweet Dee."

And they're not even the first couple from the show to get hitched -- cast-mates Charlie Day and Mary Elizabeth Ellis wed in 2006, says the mag.
