Lohan not engaged

Lindsay Lohan has hit out at reports suggesting she and new boyfriend Riley Giles are planning to wed, stating the ring she's wearing on her wedding finger is a gift from her dad.

Lohan was spotted sporting the subtle band while out and about in Hollywood on Tuesday night, but has since transferred it to another finger after causing a fuss.

The 'Mean Girls' star's publicist insists the engagement rumours are ridiculous and the new ring is a gift from her father, Michael, who recently ended a two-year estrangement from his daughter by meeting up with her in rehab in Utah.

He admits he was taken aback by the engagement story: "I don't know anything about Lindsay being engaged. If she did (get engaged), she would have come to me or Riley would have come to me himself."
