Carrey, Zellweger: Splitsville!

They almost made it through the disastrous breakup year that has characterized much of Y2K, but alas Jim Carrey and Renee Zellweger are just not meant to be.

Carrey, 38, and Zellweger, 31 — who met on the set of this summer’s “Me, Myself & Irene” last year during filming — have ended their yearlong relationship, E! News Daily reported Tuesday.

Both actors’ publicists have confirmed the breakup, with the actress’s rep being the more vocal of the two about the matter.

“As of a couple weeks ago, Jim Carrey and Renée Zellweger are no longer in a relationship,” publicist Leslie Sloan told E!.

Just last month, the now ex-couple were still practically glued to each other during the “Dr. Seuss’ How the Grinch Stole Christmas” premiere in Universal City, Calif.

Zellweger, however, was without Carrey at Tuesday’s Fire and Ice Ball.

Now we know why.

Carrey has been prone to falling for his female co-stars. Besides Zellweger, he fell for “Dumb and Dumber” co-star Lauren Holly. The two wed in 1996 and divorced a little less than a year later in July 1997. Before that marriage, Carrey was married to actress Melissa Womer for six years.
