Liv Tyler and her rock singer husband, Royston Langdon, are expecting their first child, PEOPLE has learned. Her publicist confirms that she's due sometime next winter. "Roy and I are both overjoyed and look forward to the arrival of our child," says Tyler.
The Lord of the Rings star, 26, married Langdon, 32, on March 25, 2003, in Barbados after a two-year engagement.
Among the wedding guests: Liv's dad, Aerosmith frontman Steven Tyler; her mom, ex-groupie-turned-singer Bebe Buell; and rocker Todd Rundgren, who with Buell, his former longtime partner, raised Tyler – and has toured with Langdon's band, Spacehog.
At the time, Buell told PEOPLE: "I can't wait to see my grandchildren. They're going to be gorgeous!"
Tyler finished filming the movie Lonesome Jim five weeks ago.
