Watts and Schreiber in 2007
Expectant parents Liev Schreiber and Naomi Watts
are not married – even though the actor told reporters over the weekend that they'd tied the knot.
"They're not married," Schreiber's rep told PEOPLE Tuesday, clearing up mixed reports about the couple's marital status.
The misunderstanding started on Sunday as Schreiber, 39, and Watts, 38, headed into the Tony Awards at Radio City Music Hall in New York City. Schreiber told Entertainment Tonight
: "We are married. You got it first. Break the story!"
But the couple spent the rest of the evening denying they'd tied the knot. Backstage, a Vera Wang-clad Watts was asked if she had wed. She smiled and said, "No." Schreiber meanwhile, said of the report: "Not true."
The couple, who confirmed in February they are expecting their first child
, will welcome the baby in August, ET
Speaking to reporters at the Tonys on Sunday, Schreiber talked about possible names for the baby. "I'm thinking Tony is a good name," he joked (he was nominated for a best actor award for his performance in Talk Radio
, but lost out to Frank Langella for Frost/Nixon
He added that he and Watts didn't know whether they were having a boy or a girl: "I really don't know. I wanted to know; she doesn't."
