Jennifer Lopez in Paule Ka

DALLAS, Apr 26, 2010 /FW/ — Wow! Monday rolled in and celebrities had been busy beginning with Jennifer Lopez who was just in Los Angeles last week but was spotted in Paris today at “The Back-up Plan” press conference.

Always in high fashion, La Lopez was seen wearing a white dress by Paule Ka at the press conference. She liked it so much that she did not change her wardrobe when she went shopping at the French capital.

“The Back-up Plan” starring Jennifer Lopez and Alex O’Loughlin took in $12.3 million in ticket sales here in the U.S. which is within range of Jennifer Lopez’s openings in the same genre of romantic comedies.

Speaking on movies that just hit theaters or will be in theaters soon, Amanda Seyfried whose movie “Letters to Juliet” will hit U.S. theaters on May 14th attended the movie’s premiere last Sunday, April 25th at the Tribeca Film Festival wearing a black jeweled blazer and black shorts from the Viktor & Rolf Pre-Fall 2009 collection.

“Letters to Juliet” tells the story of an American girl (Amanda Seyfried) on vacation in Italy who finds an unanswered “letter to Juliet” — one of thousands of missives left at the fictional lover’s Verona courtyard, which are typically answered by a the “secretaries of Juliet” — and she goes on a quest to find the lovers referenced in the letter.
