Latest Mary-Kate Olsen News

Jessica Biel lends her star power in support of celeb hairstylist Mark Townsend’s new online beauty destination MARKTBeauty.com held at The Penthouse of the NYC’s Smyth Hotel Tribeca on Tuesday night (June 8).

The 28-year-old actress dropped by but didn’t stay very long — she rushed home to see boyfriend Justin Timberlake, who just came back from a week-long trip in Hawaii. She did wear Oscar de la Renta — the emerald silk taffeta ruffle blouse and lapis multi tweed pleated embroidered skirt.

Glee’s Lea Michele wore a sexy Giambattista Valli dress, revealing a black lace bra. When asked by if her bra provided enough lift, she joked to Just Jared, “Well, there’s not much to hold up anyway!”

Also in the house: Mary-Kate and Ashley Olsen and Maggie Gyllenhaal.

FYI: Jessica and Lea sparkled in Tiffany & Co. jewelry!
