Ellen DeGeneres and Portia De Rossi Wed in LA

US talk show host Ellen DeGeneres has married her long-time partner, actress Portia de Rossi, according to the Associated Press news agency.

DeGeneres' publicist confirmed reports that the couple tied the knot at their Beverly Hills home on Saturday.

The presenter, 50, and De Rossi, 35, exchanged handwritten vows in a private ceremony attended by 19 guests, reported People and US magazine.

The couple have been dating since December 2004.

DeGeneres announced plans to wed on her talk show in May after the California Supreme Court overturned a state ban on same-sex marriage.
