Straddling a custom motorcycle, actor John Corbett rode onto Lincoln Road Friday to celebrate Kiehl’s 3rd annual LifeRide for amfAR. He was joined by Chris Salgardo, President of Kiehl’s USA, who accepted a proclamation from the city declaring July 13th “Kiehl’s Day” They also presented a check to amfAR for $115,000 for AIDS awareness. Other famous riders included Teddy Sears ( American Horror Story), Christopher Redman ( CSI: Miami, 88 Minutes), Grant Reynolds ( Young and the Restless, Knifepoint) and Hell’s Kitchen contestant chef Robyn Almodovar. Corbett was overheard chatting with Almodovar about their earlier careers as hairdressers. While Almodovar is a confessed beauty school drop-out, Corbett says he still enjoys cutting hair. Who knew?

On the eve of their three game series against the Marlins, Washington Nationals players Mark DeRosa, Michael Morse, Craig Stammen and Danny Espinosa dined with their wives at The Forge Restaurant & Wine Bar. They were in great spirits, says our spy.

A situation of sorts seen Friday at the W South Beach, where Mike “The Situation” Sorrentino was seemingly in a business meeting with three other “juice heads,” says our spy, including one who went “ballistic, standing up and screaming over an $8,000 bill for something he didn’t approve.” The Situation, we’re told, remained quiet while “this guy flipped out.” Once he calmed down, they wrapped up and left. That bill apparently had nothing to do with the W but with one of the mad man’s companies.

Though recently turned away at a nightclub door in L.A., Mansion welcomed Kris Humphries Saturday night, where he checked out British DJ duo the EC Twins. Humphries, we’re told, was in great spirits, hanging with rapper Lil’ Romeo drinking Belvedere and sodas and chatting with guests at neighboring tables. As for how these two managed to come together, they were among the celebs at the AmericanAirlines Arena earlier that night for the big ViSalus party.

Humphries also made sure to be seen Sunday afternoon at the Delano’s White Rabbit pool party, where he partied with three friends in a cabana.
