Samantha Ronson showed some impressive powers of concentration as she manned the decks at the launch of Sapphire New York Gentlemen's Club on Monday night.

Lindsay Lohan's ex kept her eyes firmly on the job during her DJ set, apparently oblivious to the dancer gyrating suggestively just inches away.

Sam joined fellow D-listers Pamela Anderson and Shannon Doherty at the grand opening of the strip club steakhouse.

Meanwhile, Sam has reportedly been spotted leaving Lindsay's place, prompting speculation that they may still rekindle their turbulent relationship, which came to an explosive end in March.
