Here's eternally youthful supermodel Christie Brinkley, 58, at an event in Hollywood on Wednesday (left) -- and former "Heroes" star Ali Larter back when she was 33-years-old in 2009 (right).

A 25 year age difference never looked so flawless.

We're just sayin'.

The scofflaws who hacked Scarlett Johansson's cell phone ... and then leaked several nude pics -- are in the crosshairs of the FBI, and we're told the Feds already know the identity of the main culprit.

TMZ broke the story ... Scarlett contacted the FBI yesterday after the pics -- one which features her bare breasts and another showcasing her behind -- were leaked to several websites. 

Law enforcement sources tell TMZ ... the FBI is "honing in" on the group of hackers and know the identity of at least one of them -- and we're told it's the ringleader.

Our sources say the hackers have done their dirty work on the cell phones of other celebs, including Vanessa Hudgens, Jessica Alba, Lindsey Vonn, Ali Larter and Emma Caulfield.

The growing list of celebs targeted by a hacker ring now includes the names of an Academy Award winning actress and two gold medal winning Olympians ... TMZ has learned.


Sources connected to the hackers tell TMZ ... Natalie Portman (Oscar winner for "Black Swan"), Lindsey Vonn (Gold medal skier in 2010), and Carly Patterson (all-around Gold in gymnastics in 2004) are all among the women who have been targeted by a ring of hackers who have gained access to over 100 active email addresses of celebrities, politicians and sports stars.

We're also told Dianna Agron from "Glee" has been targeted as well. And a prominent 17-year-old actress was also hacked ...  though we're not releasing her name.

As TMZ first reported, the hackers have snagged nude photos from many female stars, including  Vanessa Hudgens, Ali Larter, Busy Philipps, Scarlett Johansson, Miley Cyrus, Jessica Alba, Addison Timlin and Renee Olstead.

We're told the FBI knows the identity of the ringleader ... but no arrests have been made so far.

The hackers who are now being investigated by the FBI for allegedly pilfering nude photos and videos of 50 Hollywood celebrities have also been targeting sports stars and D.C.'s most powerful.


Sources connected to the hackers tell TMZ ... the cyber-crooks currently have 100 active email addresses of celebrities, politicians and sports stars.  We do not know the identity of the sports stars or politicians, but they are all high-profile.

TMZ broke the story ... the hackers have snagged nude photos and videos from female stars including Vanessa Hudgens, Scarlett Johansson, Jessica Alba, Christina Aguilera, Ali Larter and Demi Lovato.  There are no male celebs on the list.

The FBI knows the identity of the ringleader, law enforcement sources tell TMZ.

As for Vanessa Hudgens, our sources say the hackers may have obtained the pictures and videos through a friend who betrayed the actress.

TMZ now has more victims of the hackers who are in the cross hairs of the FBI for pilfering nude pics of celebrities.


We've learned the ring has hit the mobile and other devices of Jessica Alba, Selena Gomez, Demi Lovato and Christina Aguilera.  We've already told you the ring also stole pics and video from Vanessa Hudgens, Scarlett Johansson, Ali Larter, Busy Philipps, Miley Cyrus, Emma Caulfield, Addison Timlin and Renee Olstead.

In all, the FBI believes the ring has targeted 50 celebs -- all female.

TMZ now has a partial list of the celebs who had compromising pictures and video stolen from their computers and mobile devices by a group of hackers.


The list includes Vanessa Hudgens, Ali Larter, Busy Philipps, Scarlett Johansson, Miley Cyrus, Emma Caulfield, Addison Timlin and Renee Olstead.

TMZ broke the story ... the FBI sat down with Vanessa Hudgens Wednesday for more than an hour to determine how her Gmail account got hacked.

We're told 50 celebs had compromising photos and videos stolen by one group, and one of the ringleaders has his fingerprints on every job. 

Our sources say the hackers' primary motivation is the thrill and challenge of it all -- not the money.

Law enforcement sources tell us the FBI is closing in on the hackers.
