X17 EXCLUSIVE - Lindsay Lohan Wakes Up Early To Exercise, Flashes Diamond Ring

That's a mighty big rock on the rehabilitating starlet's finger! An early Xmas gift to herself perhaps?

24-year-old actress Lindsay Lohan woke up at 6:30 a.m. today and headed off to the gym to work on her fitness before attending her morning drug and alcohol education classes at Betty Ford. LiLo also managed to show off her flashy ring to the photogs. Even pretend diamonds can be a girl's best friend! Maybe she picked it up at the same jewelry store where she bought her pirate sword necklace?

Back in Hollywood, Lindsay Lohan 2.0 (Emma Stone) revealed her new blonde locks at the "Trevor Live" event Sunday night - classic Lindsay move! Bleaching her red hair blonde did wonders for Linds, right?

And perhaps when the Mean Girls beauty returns to town in January, she'll find a new BFF in fellow out-actress Amber Heard. We'd love to see Lindsay, Amber and SamRo hanging out ASAP!
