Ross Mathews Marries Fiancé Wellinthon García in Mexico — with Flower Girl Drew Barrymore!

The RuPaul's Drag Race judge and his husband tied the knot at Almar Resort in Puerto Vallarta, Mexico, on Saturday

Ross Mathews married fiancé Dr. Wellinthon García in a beachside ceremony on Saturday, he tells PEOPLE exclusively.

The RuPaul's Drag Race judge and his husband tied the knot at Almar Resort in Puerto Vallarta, Mexico — the same place where the couple met two years ago. Wearing custom grooms' tuxedos from Robbie and Co., the newlyweds exchanged vows in front of 110 guests.

"It was a destination wedding," Mathews, 42, tells PEOPLE. "So we invited 130 people, thinking maybe 50 people would come. But 110 people came — and I'm thrilled!"

Because Mathews lives in Los Angeles and García in New York, the couple struggled to decide where to hold the ceremony. "It caused me such anxiety," recalls Mathews. "But Drew Barrymore told us, 'Do it where you're supposed to do it, and the people who are supposed to be there will be there.' So we chose the place where we first met."
