Super star Katy Perry gave a super performance at halftime of the Super Bowl on Sunday night. The mega-pop star performed a medley of her biggest hits — "Roar," "Dark Horse," "Teenage Dream" and "California Girls" — that ended with her hit "Firework," complete with pyrotechnics and Perry rising high above the stadium to sing the song. She ended by circling the stadium and waving to the crowd.

Her "special guest" — hyped all week — was rapper Missy Elliott. Perry also was joined by Lenny Kravitz, and the two combined on the duet "I Kissed a Girl" as flames exploded behind them.

Before the game, John Legend delivered a stirring rendition of "America The Beautiful," and Idina Menzel followed with a rousing performance of "The Star-Spangled Banner."

Justin and Jessica await blessed event

It was Justin Timberlake's 34th birthday on Saturday, but it's another birth date that's on his mind — that of his future son or daughter. The superstar shared a picture of a bulging belly — presumably belonging to wife Jessica Biel — on Instagram. He wrote that he was getting the greatest gift ever this year and added: "CAN'T WAIT." The sex of the baby is not yet known; the actor-singer joked that the couple is taking bets. The Grammy-winning Timberlake married Biel in 2012. It will be the first child for both. Biel's pregnancy has been rumored for weeks but Timberlake's post is the first official word.

Oops, MPR apologizes

A performance by singer Robbie Fulks that aired live on public radio's "A Prairie Home Companion" included a line in one of his songs that prompted an apology from Minnesota Public Radio (MPR) ahead of Sunday's rebroadcast of Garrison Keillor's show. Fulks sang "Where I Fell" about 50 minutes into the nationally broadcast show Saturday evening at the Fitzgerald Theater in St. Paul, and with it the blasphemy that ends with the syllable "damn."

Before the late-morning rebroadcast Sunday to MPR's listeners, an apology was aired and the word was bleeped out the second time around. "Prairie Home" spokesman David O'Neill said the show issued a "language advisory" soon after the live broadcast Saturday to 670 local stations across the country about the word. "The program directors … then make that call," about how to deal with language concerns, O'Neill said. MPR spokeswoman Angie Andresen said the decision to bleep the word "is something we do on occasion with certain words, especially when children are likely to be listening with their families."
