Lindsay Lohan's Instagram posts reveal that she may have found a summer fling, as a mysterious Greek hunk has been regularly seen in the actress' numerous photos.

According to Daily News, the "Mean Girls" lead star has been in Europe to take on the starring role in David Mamet's West End production of "Speed-The-Plow". The 28-year-old has also used her time in Europe to have a vacation, as Lindsay Lohan Instagram photos show that enjoying the beach and partying with friends.

A regular friend who has been seen in Lindsay Lohan Instagram posts, however, has caught the attention of many. The bearded, slightly older Greek hunk said to be the actress' summer fling has been identified as Vasillos, and the former child star has been shamelessly posting selfies of them spending quality time in Greece.

One of the first Lindsay Lohan Instagram posts of herself with Vasillos was captioned: "I love Greece... Pure beauty". The photo showed her with the then unidentified Vasillos, in what seemed to be a yacht party with a beach background. They were both scantily clad in summer wear.

Another selfie showed Lindsay Lohan slightly tilting her head towards Vasillos, with the caption: "Thank you for showing me these beautiful waters".

Paparazzi have also snapped the inseparable duo walking around a public event last week, with Lindsay Lohan wearing a black lace kaftan and a topless Vasillos wearing just pale blue shorts.

Lindsay Lohan's Instagram posts and paparazzi photos of the actress with Vasillos were all taken on different days, leading people to conclude that the two are regularly spending time with each other.

Lindsay Lohan will kick-off her theatre gig this coming September. In the meantime, she spends her down time traveling around Europe.

Lindsay Lohan's Instagram photos showed she has been partying all over Spain, Austria, the United Kingdoms, and Greece.
