Jim Carrey and Renée Zellweger apparently won't be cozy together for the holidays. A spokeswoman for Carrey confirmed yesterday that her client and the actress have ended their yearlong relationship. TV's "Access Hollywood" first reported the breakup. Zellweger's publicist has also confirmed the spilt. "It's a private matter," said Marleah Leslie. The couple met in the fall of 1999 on the set of "Me, Myself and Irene" and were together as recently as last month's premiere of "Dr. Seuss's How the Grinch Stole Christmas," which stars Carrey. Zellweger's most recent film was the critically lauded black comedy "Nurse Betty."
