Text Message Heats Up Lohan/Ronson Romance Reports

Reports of a romance between Lindsay Lohan and her best friend Samantha Ronson have hit fever pitch following the publication of a reported BlackBerry message.

According to a close source, Lohan received a text message from DJ Ronson on her 22nd birthday congratulating the Mean Girls star on their "four-month anniversary".

The insider, who saw the message tells Life + Style magazine, "Lindsay left a message from Samantha up on her BlackBerry all day."

"It said, 'I love you, honey. Happy four-month anniversary!' They are madly in love."

Reports suggesting Lohan and Ronson were more than just friends began circulating after the couple was spotted kissing and cuddling during a party at the Cannes Film Festival in France in May.

Since then, the pair has been inseparable.

The couple reportedly exchanged matching Cartier 'Love' bracelets on Lohan's birthday.
