How Cute, Lilo and Sam Have Matching Luggage

Lindsay Lohan and her boyfriend girlfriend Samantha Ronson are on vacation, again.  Which totally makes sense, because who wouldn't want to be on a permanent honeymoon if you could afford it.

The pair checked into a Miami hotel yesterday after jetting in and out of Chicago over the weekend to hit up some DJ party.

According to News of the World, Sam and Lilo really actually are going to be celebrating their honeymoon for real later this year.  Here's what an 'insider' supposedly told the tabloid:

• 'They've been keeping the relationship quiet for months and trying to pass each other off as "just good friends."  But they've decided it isn't a fling, it's for life— so they want to make their romance public.'

The source claims that even Dina Lohan is on board and anxious to 'welcome Sam into the family' with a lavish party, while Lindsay's been busy picking out her Chanel wedding dress, and Sam jokes she'll wear a black groom soon and top hat. 

The story's probably bogus considering Lindsay and Sam haven't even come out yet...but if it does happen god would that be great and make me laugh a lot.
