Taylor Swift is just 21, but she's already been named Woman of the Year by Billboard.

The multiplatinum singer/songwriter is the youngest person ever to get the award, which in the past has gone to Beyonce, Reba McEntire and Fergie.

She'll be honored at the Billboard Women In Music 2011 event in NYC Dec. 2.

Swift was the youngest person ever to win the Album of the Year Grammy -- she won for Fearless in 2010. She has also won ACM, CMA and AMA awards.

She's currently on a national tour for Speak Now, which has sold more albums than any other artists this year.

Jenny returned to the block ... in a Fiat.

Jennifer Lopez is keeping us on her toes as the new Fiat spokeswoman, this time driving a 2012 Fiat 500 through her old Bronx neighborhood.

"This place inspires me to be tougher, to stay sharper, to think faster," she says in the "My World" commercial. "They may be just streets to you but to me they're a playground."

We'll give her this -- she looks extremely happy to let her hair down (literally) and hug all the kids she comes across on the street.

Conrad Murray's involuntary manslaughter trial started its third week on Tuesday, where more of Murray's 2009 interview -- an interview after Jackson's death -- was played for the court.

In it, Murray recalls telling Jackson's mother and children that MJ was dead.

He says Michael's daughter, Paris, asked him: "Dr. Murray, you said you save a lot of patients. You save people with heart attacks, and you couldn't save my dad?"

"I tried my best," Murray told her.

Jackson's autopsy doctor, Christopher Rogers, took the stand, telling the jury the singer was very healthy for his age. Rogers explained that he ruled the case a homicide because the Propofol was administered by a person other than the patient.

Rogers also noted that he thought Dr. Murray did not have the appropriate equipment at Jackson's home to keep him alive in case of an emergency.

One of the prosecution's key points lies in how long Murray was gone from Jackson's bedroom on the day he died (after administering the Propofol.) The prosecution says he left for so long that when he returned, Jackson had been dead too long to revive. They argue that this is neglect.

The defense says Murray was only gone for two minutes.

Marvel maniacs and casual superhero fans alike -- get ready to geek out.

The first official Avengers trailer has been released, and it's everything we could have dreamed of after Nick Fury (a.k.a Samuel L. Jackson) uttered, “You have become part of a bigger universe,” at the end of the original Iron Man three entire years ago.

In the trailer, Fury again lays out the stakes, telling us that a "group of remarkable people" has been brought to protect the earth from bad guys (a.k.a Thor's black sheep brother Loki, played by Tom Hiddleston), battles and, you know, general extinction.

The flick stars Robert Downey, Jr. as Iron Man, Chris Evans as Captain America, Chris Hemsworth as Thor, Jeremy Renner as Hawkeye, Scarlett Johansson as Black Widow and Cobie Smulders as S.H.I.E.L.D. Agent Maria Hill, and you can see all of them kicking some major butt in this two minute preview (above).
