One lucky fan got to passionately kiss Ricky Martin for charity, and it only cost her $90,000.

Ana Paola Diniz was the highest bidder at an auction raising money for AIDS charities at the amfAR Inspiration Gala in Sao Paulo, Brazil over the weekend, winning the chance to plant a kiss on Ricky.

The singer certainly made sure she got her money's worth though, as he passionately put his arms around her and gave her a kiss to remember.

The event was already significant for the 44-year-old, as it marked the first time he made his relationship public with his boyfriend, Syrian artist Jwan Yosef.

After months of speculation, Martin made it official at the amFAR Gala, and posted a photo of the couple from the event with the caption, "Yup."

Luckily, the night's expensive lip lock was for charity, so surely Yosef didn't mind giving up his beau for the big kiss.
