If you love Rachel Bilson's laid-back California girl style or covet Olivia Palermo's chic New York City taste, you'll want to log onto immediately. The Heart of Dixie actress and The City alum have just joined fashionable forces with the site as its new celeb editors.

Bilson, 30, and Palermo, 25 (along with model and actress Byrdie Bell) follow in the stylish footsteps of Rachel Zoe, who partnered up with Piperlime last year.

The four fabulous fashionistas will each curate their top wardrobe picks for the e-tailer, which sells a mix of luxe and affordable accessories, shoes, and clothing for both women and men.

Customers can also peep behind-the-scenes videos and nab styling tips straight from the stars, who are no strangers to dispensing wardrobe advice.

Palermo recently told Us Weekly to "splurge on key pieces you can grow into as you get older and always complete your look with great accessories." And Bilson had admitted to shaving time off her routine by making sure her entire outfit is planned out for the next day -- before she hits the pillow!
