Beyoncé Knowles was back out in NYC this evening to catch the second night of Jay-Z's Carnegie Hall charity concert series. She shared pictures on her website of her sparkly Monique Lhuillier dress, Chanel purse, and Lorraine Schwartz jewels, which she accented with blue nail polish. Beyoncé's nail color and huge ring in the same hue seem to be in honor of her baby daughter, Blue Ivy. She gave birth to Blue one month ago and stepped out for the first time just yesterday. Beyoncé wore red to attend Jay-Z's first show, and the couple celebrated the big event with an afterparty at Jay-Z's 40/40 Club.

Jennifer Aniston slipped on a slinky peach Calvin Klein dress for the cover of InStyle's March issue. She's promoting her new comedy, Wanderlust, which hits theaters later this month. Jennifer met her boyfriend, Justin Theroux, while working on the project, and the duo have been going strong from NY to LA ever since. Jennifer opened up to the publication about what she's looking for in a man, Justin's signature style, and her age. Here's more from Jennifer Aniston in InStyle:

• On her age: "You know what makes me feel old? When I see girls who are 20-something, or the new crop of actresses, and think, Aren't we kind of the same age? I don't feel my age. I feel young every day."
• On finding the right partner: "Having experienced everything you don't want in a partner over time, it starts to narrow down to what you actually do want. As I get older I realize what qualities are important in love and what suits me. And what I won't settle for."
• On dressing like Justin: "First of all, he has great style — it's very specific, and it has been his style forever. Has it influenced mine? No, but I know people say it has. 'Oh, look, you're dressing alike.' And I think, No I'm not. I've had this jacket for three years!"

Jessica Simpson stepped off of a private plane in LA yesterday while her fiancé, Eric Johnson, followed behind carrying her bags. The couple made a quick trip to Indianapolis, where they watched the Super Bowl from a private box. They were just two of many celebrities at the Super Bowl this year, including Chace Crawford, Nina Dobrev, and Matthew Bomer. Jessica and Eric were rooting for the Patriots, but the New England team was defeated by the NY Giants in the final minutes of the game. Eric is a former NFL player himself, having been on the 49ers and the Saints during his seven-year career. He's since turned his focus to family now that he and Jessica are expecting their first child together.

Beyoncé Knowles went out in NYC last night to watch her husband Jay-Z's performance at Carnegie Hall. It was Beyoncé's first public appearance since giving birth to daughter Blue Ivy Carter exactly one month ago. She wore a tight, rust-colored dress from the Alice by Temperley line, paired with Christian Louboutin heels, bright blue nail polish, and a huge sparkling ring in the same hue as her daughter's name for the occasion. Beyoncé released the first pictures on her website and was also photographed leaving the venue with a big smile on her face at the end of the evening.

Baby Blue stayed home, but her presence was noted while Jay was onstage — he performed his track "Glory," which features her infant noises from when she was only 1-day-old. Afterwards, Jay noted on stage that he wasn't sure he was going to make it through the song without getting emotional. Beyoncé was a few minutes behind Jay-Z as they headed off to celebrate his show at his newly reopened 40/40 Club. As she headed inside, Beyoncé spoke about Jay-Z's return to the stage, saying, "It was amazing."
