Lindsay Lohan Receives A $25,000 Necklace

If the threat of more jail time doesn't keep Lindsay Lohan straight, maybe this will.

Looking happy and healthy, the recently rehabbed starlet, 24, showed off some heart-shaped bling around her neck in L.A. Friday morning – a sort of keep-up-the-good-work gift.

The actress's pal Pascal Mouawad – the famous jewelry designer behind Nicole Richie's House of Harlow line – gave the Mean Girls starlet the 10-carat diamond Rosette necklace, estimated to be worth $25,000.

"Lindsay is looking great, she has a positive attitude, and we are looking forward to an amazing 2011 spending a lot of time together," Mouawad, 38, tells PEOPLE.

Even though Mouawad says Lohan is "really driven with her career right now," a source close to the duo says, "The two have no plans to work together professionally."

Adds the source, "Lindsay is dear to Pascal's heart, and he thinks she is headed down the right path. He wants to keep her going in that positive direction."

Nicole Richie: From Partier To Domestic Goddess

The Hollywood socialite has come a long way from The Simple Life!

Nicole Richie talks about home life with the kids, her clothing/jewelry line and growing up in the new issue of In Style magazine...

"I don’t have a hat and apron, but I entertain at home a lot," says Nicole, who only cooks "very, very healthy" food for Joel Madden and their kids, Harlow and Sparrow - all "made with love," of course!

And while Nic has her own clothing line (Winter Kate) and jewelry range (House of Harlow), she also has her own budding fashionista daughter! "Harlow picks her own clothes. It's a 20-minute thing," Richie reveals.

Finally, Nicole proves she isn't afraid to comment on her troubled past: "One thing about me is that I’ve always taken responsibility for my own actions whether they’re good or bad. Even when I was going through my tough time, that was a situation that I created. People ask me, do I blame Hollywood or my parents? No I don’t blame my parents. It had nothing to do with them. I created it and manifested it and I got myself through it with the help of a lot of great people."

Well said, girl! And sidebar, loves the Lady Gaga-look in these pix!
