According to Ananova, Lohan and her man were recently spotted together and seemed to be happier than ever.
A spokesperson for the star of the films Just My Luck and Freaky Friday, among others, confirmed that Lohan is still dating the heir to the Hard Rock Cafe chain. The spokesperson said that the rumours are simply "not true".
The speculation of a split came after the two parted ways after a dinner together at the Chateua Marmont Hotel.
Other sources were saying that Morton ended the relationship with Lohan because she was, "too much drama."
Lohan and Morton have been dating since July.
