From the director of Beyonce's "Single Ladies (Put a Ring on It)" comes Leona Lewis' music video for her new single "Happy." And boy is it sad.

Sad-good, though. Viewers get a surprise ending in this mini-movie, with Lewis loving and losing her love, the stage set in Cuba. It provides the color and the vibrancy and believability of the shifting scenes, with actors' and Lewis' faces telling the tale. Though it is hard to believe the "X Factor" star and "Bleeding Love" singer would live in a time-worn shoebox like there is in the clip.

The timing is beautiful, too, with the climax, the big-breathed beat, falling right at the pivotal moment at the end. We have song producer and co-writer Ryan Tedder (OneRepublic) to thank for that too. Lewis does a fabulous job, may this mean a penchant toward acting, a la J-Lo?

Director Jake Nava is sending us out to a boo-hooing weekend. Seriously, folks, take it easy on us, it's Friday.

P.S., don't those opening strains of the song bare a striking resemblance to Sinead O'Connor's "Nothing Compares 2 U?"

Lewis' album "Echo" drops Nov. 17. "There are a number of cuts on ['Echo'] that are very strong. She is a hard-working young woman. She broke every rule in the world," said Sony Creative Chief Clive Davis last week in an interview with HitFix. "We just keep the bar up there to hopefully have the second album avoid any sophomore slump."

In other Lewis news, the singer was attacked last week as she was signing her autiobiography at a bookstore in London. She was punched in the face by a man who had previously auditioned for Britain's "X Factor"; he is awaiting a court date and has been sanctioned under the country's Mental Health Act. Lewis is said to recover fine, though had to cancel some promotional appearances.
