Uh oh! Trubs in paradise for Lindsay Lohan and Samantha Ronson? L. Ron made their way to Miami, FL to celebrate the New Year together but spent quite a bit of time apart … and what is most troubling is that Lindsay got caught playing smoochy-face with a mysterious new dude while sunnin’ herself on the beach — behold:

Lindsay Lohan rang in the New Year in a relaxed style, prancing around on a beach in Miami. The Hollywood starlet slipped into a simple black bikini as she celebrated the last day of 2008. But despite Lindsay’s smiles her girlfriend Samantha Ronson was elsewhere. Instead the 22-year-old lapped up the attention from a male fan… but Sam has no need to worry – he was just a few years old. Lindsay was soaking up the sun when the boy, sporting a pair of Spider Man swimming shorts, ran over to her and kissed her on the check. Lindsay seemed delighted with the attention, and beamed after the affectionate gesture. But despite Sam’s absence it appears the couple are still going strong. They were spotted together days earlier in Florida shopping for sexy lingere, plus a new black and gold chain halter neck bikini which Lohan then wore to the beach.

OMG … how cute are Lindsay and this little kid? Adorable! And Linds is lookin’ pretty amazing in that skimpy bikini … hot hot hot. BUT … perhaps everything isn’t as rosy betwixt Lindsay and Sam as this report claims. According to TMZ, the ladies got into another very public argument aboard an American Airlines plane this week:

2009 didn’t start out well for Lindsay Lohan and Samantha Ronson. Our airport spies say they got into another nuclear fight — this time at Miami International Airport. We’re told it started in the American Airlines Admirals Club. Once on the plane, as one person put it, “Lindsay was so inconsolable the flight attendants asked if she’d like to disembark.” We’re told there was lots of crying, tears, etc. … They flew back to L.A. yesterday.

This would be the second public fight that TMZ claims L. Ron suffered in the past week or so. Honestly, all couples fight … sometimes more than others … but the fact that they can keep it together and move past the arguments is a good sign that they are rock solid. Here’s wishing L. Ron a very happy 2009 together full of more lurvin’ and less fightin’.

UPDATE: Oh the drama! THIS person bore witness to one of the fights that L. Ron got into on New Year’s Eve at Mansion nightclub and managed to get some of it on video! After the jump, check out a short vidclip of the pair lookin’ all sorts of combative in the DJ booth on NYE …

You can read all the sorted deets HERE. Yeah, it doesn’t sound good … for various reasons. I wonder if we really should be concerned after all?
