I don't think she's hooking up with the DJ in that photo...yet. Lindsay famously quit men for a few years to be with DJ Samantha Ronson. Then she came back to the fellas and hooked up with DJ Jus-Ske. Who looks like a well quaffed, MCA of the Beastie Boys. May he RIP.
Lindsay has tried a few musician's out recently, most famously Max George of The Wanted whom she followed all over America and Europe, and even got in a fist fight with another woman who was flirting with Max in NYC. But that was so last Christmas. Even Max told the NY Post "we had a brief snog, but wish her the best...wherever she is now". In other words we're now in the "quit it" phase of the "hit and quit it" plan. So it's February, the month of love and Lindsay is back in love with another DJ. Julian Cavin is only 22 so perhaps that explains why he hasn't come up with a cool DJ name yet.
So we'll have to watch to see what kind of plan he has. Hit it & Quit it? If it was me I'd opt for the "zip it and ship it" plan. As in keep your pants zipped and get the hell away from her before you catch something.
