Doug Reinhart With Paris Hilton, Mark McGrath And Carin Kingsland

St. Patrick's Day at LAVO inside The Palazzo saw a bevy of sexy leprechauns and an Irish host. Mark McGrath of Sugar Ray fame was joined by his longtime girlfriend Carin Kingsland and several other couples, dining at a center table downstairs at LAVO before heading up to the nightclub where the St. Patty's Day party was already in full swing. DJ Five handed over the microphone to McGrath who was happy to encourage debauchery from the Guinness fueled crowd. McGrath was later caught by surprise when sparklers and cupcakes came out, an unexpected treat to celebrate turning 41 this past Sunday. He made sure to proclaim his Irish spirit, showing off a number of shamrock tattoos and wearing green shoelaces.Around 1 pm, Paris Hilton arrived at LAVO with current squeeze Doug Reinhart in tow. Paris shined in a rhinestone headpiece, and wore a green skirt in celebration of the holiday. The duo and friends from her show "My New BFF," took a VIP table in front of the DJ booth near Mark McGrath and the happy couples posed for pictures together. She even had the servers create a mixer of bloody mary mix, lime juice and oj to go along with the Grey Goose and Patron at the table. Paris, who was spotted canoodling with her beau throughout the night, hopped on the microphone to join McGrath in announcing LAVO's contest to find the sexiest leprechaun.
