Singer Ricky Martin has urged the Argentine Senate to approve a gay marriage bill.

The recently out Martin tweeted in Spanish to over 1 million followers: “Let's go Argentina! The same rights with the same name for everyone.”

Senators began debating the bill at about 1PM on Wednesday and are expected to continue well into the night. The nation's lower house, the Chamber of Deputies, approved the bill in May. Leading into the debate was a recommendation by a key Senate panel to reject the marriage proposal and approve a bill that recognizes gay and lesbian couples with civil unions but does not allow adoption.

The Senate vote is considered by most to be too close to call.

Martin put to rest persistent rumors that he's gay in March. The 38-year-old Martin announced he's gay on his website, followed by a post on Twitter.

In a cover story for the Father's Day issue of People en Espanol, the pop star talked about his twin sons, Valentino and Matteo, and for the first time disclosed that he has a boyfriend.

Martin said he's involved with a Puerto Rican man. He told the magazine that his love is a childhood friend. The pair lost touch but became reacquainted over a year ago in Miami. The investment analyst also helps with raising the children.

Martin's next project is playing Che Guevara in the Broadway revival of Evita.
