Katie looked every inch the vamp in a slinky blue velvet dress with sheer panels. Her long glossy hair tumbled in loose waves over her shoulders and smoky eye makeup completed the look.
Katie, who had to leave her apartment when the storm hit, joined a host of stars at the 12-12-12 Sandy relief concert. Music and comedy royalty came together, asking for help to rebuild a New York metropolitan area most of them know well.
The sold-out Madison Square Garden show was televised, streamed online and aired on radio all over the world. Producers said up to two billion people could experience the concert live.
Comic and New Jersey native Jon Stewart said: "You can throw anything at us - terrorists, hurricanes. You can take away our giant sodas - it doesn't matter - we're coming back stronger every time."
Bruce Springsteen set a roaring tone, opening the concert with Land Of Hope And Dreams and Wrecking Ball. He addressed the rebuilding process in introducing his song My City Of Ruins, noting it was written about the decline of Asbury Park, New Jersey, before that city's renaissance over the past decade.
What made the Jersey shore special was its inclusiveness, a place where people of all incomes and backgrounds could find a place, he said. "I pray that that characteristic remains along the Jersey shore because that's what makes it special," Bruce said.
He mixed a verse of Tom Waits' Jersey Girl into the song before calling New Jersey neighbour Jon Bon Jovi to join him in a rousing Born To Run. Bruce later returned the favour by joining Jon on Who Says You Can't Go Home.
Movie funnyman Adam Sandler performed a ribald rewrite of the oft-sung Hallelujah that composer Leonard Cohen never would have dreamed. The rewritten chorus says, "Sandy, screw ya, we'll get through ya, because we're New Yawkers".
Adam wore a New York Jets T-shirt and used Donald Trump, Michael Bloomberg, the New York Knicks, and Jets quarterback Mark Sanchez for laughs.
The music line-up was heavily weighted towards classic rock, which has the type of fans able to afford a show where ticket prices ranged from $150 to $2,500 (£93 to £1,500). Even with those prices, people with tickets were offering them for more on broker sites, an attempt at profiteering that producers condemned as "despicable".
"This has got to be the largest collection of old English musicians ever assembled in Madison Square Garden," Mick Jagger said. "If it rains in London, you've got to come and help us." On fighting form for a series of 50th anniversary concerts in the New York area, the Rolling Stones ripped through You've Got Me Rockin and Jumping Jack Flash.
