Joining Katie on yesterday's red carpet was Emma Roberts, who donned one of Narciso's bright Kohl's dresses. The Good Wife's Julianna Margulies, another longtime friend of Narciso's, was also on hand.

Katie was able to break from her busy schedule of Broadway preparations and mom duty for the evening out. She's set to star in Dead Accounts, her second Broadway show ever, which starts previews Nov. 3. Last night, Katie was without her usual Big Apple companion, her daughter, Suri Cruise. Katie and Suri spent a busy weekend together in NYC, though. Emma Roberts is also preparing for her next big project, We're the Millers, with costar Jennifer Aniston.

The Shops at Target launches on May 6. In addition to Emma and January, other stars like Leelee Sobieski, model Hilary Rhoda, and Giada de Laurentiis were in attendance.

It was a family affair at the Jesus Henry Christ premiere in Hollywood last night. Coproducers and sisters Julia Roberts and Lisa Roberts Gillan were joined by their brother Eric's daughter, Emma Roberts, as they celebrated the debut of the dark comedy. Julia's husband Danny Moder also served as cinematographer on the project, though he didn't join the ladies for the evening out. The screening was held inside Mann's Chinese Theatre, where castmembers like Michael Sheen walked the carpet. He was without his girlfriend and former Midnight in Paris costar, Rachel McAdams, but looked dapper as he spoke proudly about the film solo. Jesus Henry Christ tells the story of a child prodigy who goes in search of his biological father, played by Michael. Julia was behind the camera this time around in her role as a producer, but she mentioned feeling a little nervous on the night of the film's debut anyway. Stay tuned for today's PopSugar Rush to catch our coverage from the event!

Sunday's premiere of Mad Men set ratings records for AMC, and made an instant star of Jessica Paré, who plays Don Draper's young wife Megan. Her rendition of the '60s song "Zou Bisou Bisou" turned out to be the show's most talked-about moment.
