Lindsay Lohan was in Hawaii with her boyfriend, Pink Taco head Harry Morton, and the paps got plenty of photos and videos of them during their vacation. It looks like they were putting on a little show for the cameras as Harry grabs Lindsay’s boob suggestively and tilts her back while they kiss.

Rumor has it that Harry bought Lindsay an engagement ring at Cartier and was planning on popping the question. It may have happened as X17 has pictures of Lindsay wearing a big ‘ol ring on her left ring finger as she leaves Hawaii. It’s non-traditional if it’s an engagement ring, but Lindsay isn’t really a conventional girl.

X17 also has video of Harry and Lindsay at the airport. Poor Lindsay holds up her own camera and pitifully snaps random shots of all the surrounding paparrazi as a piss-poor defense. When the annoying cameraman following them asks Harry if they’re going to elope or get married, he says “maybe.”

Lindsay’s mom told Star magazine that she’s not engaged, but it could be true and she might not know about it:

It could be a promise ring or something. Lindsay seems to be smitten if she skipped the VMAs for this guy. Then again, she wasn’t missing much.
