New York, May 6 (IANS): Actor Jude Law has finally admitted to reuniting with Sienna Miller and says he is "very happy".

Law and his on-off partner made their first public appearance at the recently held 2010 Costume Institute Gala here since reuniting as a couple in December last year,

"I’m very happy," accesshollywood.com quoted Law, 37, as saying.

Asked if the two are engaged, Law said: "Not at the moment. That’s all I can say."

The couple’s first engagement was called off in 2005 following allegations that Law had been having an affair with his children’s nanny.

Law couldn't have asked for more. He has been nominated in the best leading actor category at The Antoinette Perry Awards for excellence in theatre, also known as Tony Awards, for his performance in "Hamlet".

Law hopes the nomination will fetch him his dream theatre roles he craves to play.

"I've over-thought the roles that have been offered to me in the last 15 years and maybe didn't do as much theatre as I should have done and now it's a race," imdb.com quoted him as saying.

"Before I'm in my mid-40s there are a couple of roles I've got to play before I get too old," he added.
