Leona Lewis is finally back with Happy!

London’s The Mirror have learned that her Poshness will fly back to New York City this Wednesday to finish filming her up coming cameo on the hit CW series, Gossip Girl.

Victoria Beckham was persuaded by fellow fashionista, Blake Lively and Viki agreed to appear but with a condition.

“She isn’t an actress and wanted her role to be very tongue-in-cheek. An idea for her to play Brit actor Ed Westwick’s long-lost mother was quickly vetoed. Victoria joked that she’d rather play his ex-love interest.”

“Blake and co-star Leighton Meester are fans of Victoria’s designs and have both worn her dresses. Blake attended the unveiling of Victoria’s new collection in New York last month, alongside the series’ stylist Eric Damen.”

“The trio started chatting and Victoria revealed she was a huge fan of the show. From here, Blake pleaded with her to guest star in an episode and ran the idea past producers.” source added.

According to the synopsis of Gossip Girl’s site: “It’s the first day of school at Constance Billard which means it’s also time for Jenny to take her rightful place as the new Queen Bee.

Meanwhile, Lily returns home to Rufus and her family to find that things are definitely not as she left them. Plus, a famous movie actress, Olivia Burke (recurring guest star Hilary Duff), enrolls at NYU in hopes of having a somewhat normal college experience, and is assigned to be Vanessa’s roommate.
