Mark Wahlberg wore an all-black ensemble to the NYC screening of Pain & Gain at the Crosby Street Hotel last night. He was joined by rapper 50 Cent, Peter Facinelli, who had girlfriend Jaimie Alexander by his side, and New York Giants football star Victor Cruz for the movie's NYC debut. Olivia Palermo and boyfriend Johannes Huebl also joined Mark to take in his latest film. Missing from the action was his costar Dwayne Johnson, although he and Mark linked up last week to premiere Pain & Gain in Miami ahead of its April 26 release.

Last night was an unexpectedly somber occasion for Boston native Mark on the heels of the Boston Marathon bombings. Mark took to his Twitter account yesterday to wish his hometown well, saying, "Thoughts and prayers with my hometown Boston today." Mark was torn between supporting his film and expressing his worry for his family members back in Boston, and he conveyed his true feelings about the tragedy in an interview with reporters last night, explaining, "I really didn't even want to come tonight. I hadn't really heard much — I spoke to my mom, and most of my family seems to be okay. It's such a big event, there's so many people there. It's horrible man. It's [expletive] disgusting, man. I just — I'm very upset."

Olivia Palermo was joined by Nicky Hilton and Emmy Rossum for the New Yorkers For Children annual Spring dinner, presented by Valentino, last night in NYC. Olivia, who got into the spirit of the season by donning a bright yellow Katie Ermilio gown, had boyfriend Johannes Huebl on her arm for the charitable evening out. Nicky was accompanied by boyfriend James Rothschild, and models Erin Heatherton and Hilary Rhoda were also on hand to attend the annual event that aims to support youth in foster care.

Emmy has been putting in time in her hometown after wrapping the current season of her hit show, Shameless, with the season finale airing on Sunday night.

Olivia Palermo was in a bikini once again yesterday to enjoy the end of her St. Barts vacation. She had the company of her shirtless boyfriend Johannes Huebl on the sand, and the couple even shared some PDA while out for a swim. Olivia and Johannes rang in 2013 on the luxe Caribbean island, which is playing host to other celebs including Ryan Seacrest and Julianne Hough. It's the same destination that Johannes and Olivia chose to see in 2012 as well, and they seem to be soaking up as much sun as possible before they return home to chilly NYC.

Olivia Palermo and her boyfriend, Johannes Huebl, enjoyed a sun-filled afternoon at a nude beach in St. Barts on Wednesday. While the beach was clothing-optional, both Olivia and Johannes chose to keep their suits on, with Olivia showing off her toned frame in an orange-and-pink bandeau bikini. The pair soaked up some rays on the sand and struggled with their rainbow-colored umbrella, which kept getting blown away in the wind. Yesterday, they were back on their towels. Olivia wore a bright cover up to dip her toes in the water while Johannes swam in red trunks.

At the beginning of July, Olivia saw a Valentino show in Rome. Next, it was time to travel to Verona, Italy, with her German-born boyfriend, Johannes Huebl, to see a presentation from the lingerie line Intimissimi. She then jetted to Spain, where she's been hanging out for the last week with Johannes. There may be some work involved for Olivia soon. She was recently unveiled in a new round of ads for the Spanish jewelry company Carrera y Carrera.

Earlier in the day Anne picked a chic black gown for a viewing of Valentino's Fall/Winter collection and later changed into a delicate white lace dress for a sightseeing tour through Paris with her boyfriend, Adam Shulman. Anne's attention is focused on fashion right now, but soon enough she'll return to her big-screen projects. Next month we'll see her making the promotional rounds on behalf of One Day while her other flick The Dark Knight Rises continues filming.

Olivia Palermo and her boyfriend, Johannes Huebl, hit the beach once again in St. Barts yesterday afternoon. She was decked out in her latest bright bikini as they soaked up the sun.

The couple have indulged in plenty of PDA while on their Caribbean vacation, whether they're on the sand or in the water.
