Blake Lively turned heads on Saturday when she showed up at the ‘Gossip Girl’ 100th episode party wearing a see-through gown, by Marchesa. (Are you as surprised as I am that ‘Gossip Girl’ has lasted this long!?)

I’m kind of surprised she didn’t wear Chanel, since she’s the face of the clothing line.

Leighton Meester looks pretty – but Blake certainly steels the show. Even if you’re not a fan of Blake’s dress, it’s certainly more interesting that Leightons.

Blake Lively and the rest of the Gossip Girl cast filmed outside the Standard Hotel in NYC yesterday afternoon. She filmed with her new love interest, Sam Page (you know him as Joan’s husband in Mad Men!). Lively, 23, is still dating costar Penn Badgley, and they arrived on set together.

Gossip Girl co-stars Ed Westwick and Jessica Szohr have reportedly reunited on the set of the hit TV show.

The pair, who began dating in 2008, were believed to have gone their separate ways in April. Szohr was rumored to have moved on with Sebastian Stan, the ex-boyfriend of her colleague Leighton Meester.

The reports were vehemently denied by her representative, and it seems Szohr is now back in Westwick’s arms – the pair was seen flirting as they checked into a hotel in Chicago after filming together in July.

According to the New York Daily News, the pair hooked up later in the hotel’s bar, with an onlooker saying, “They were taking shots. They’re definitely a couple. They were kissing and holding hands.”

Looks like there could be trouble in paradise for Gossip Girl co-stars Jessica Szohr and Ed Westwick. “They are still together, but things have seemed very tense between them the past few weeks,” explains an insider, who says Jessica’s been unable to hide her emotions on set. And a crew member recently witnessed Jessica in tears returning to her dressing room. Making matters worse, Ed doesn’t seem concerned with his girlfriend’s feelings. On January 29, he and a friend were seen entertaining two ladies at the Melrose Bar & Grill in LA — and Jessica was nowhere in sight. “It looked like he was on a double-date,” says an onlooker. According to an eyewitness, Ed and a friend took off with two girls after dinner in LA.
