Lady Gaga is set to expand her worldly horizons by becoming ordained so that she can perform a wedding ceremony for one of her best friends. 

The 'Marry The Night' hitmaker plans to officiate the nuptials of her close friend and yoga teacher Tricia Donegan in New York City, now that the state has legalised gay marriage, and she told Perez Hilton:

"I'm actually getting ready now to be ordained to marry one of my best friends, Tricia, who is also my yoga instructor."

25-year-old Gaga, who is an active campaigner for equality, also added that it would be "fabulous" to host gay weddings at her concerts:

"That would be fabulous. I like that idea - we can pay for the reception! Maybe we'll have (designer Jean Paul) Gaultier make me a priest outfit, so it can be official. Or controversial!"
