Scarlett Johansson smolders in a two-piece, black ensemble on the cover of Interview magazine.

The 27-year-old bombshell, who looks even more slender than usual, is not only an actress, but she'll soon be working behind the camera for her directorial debut. Johansson will direct an adaptation of the 1940s novel "Summer Crossing" by Truman Capote, according to Entertainment Weekly.

The Avengers star has also embarked on designing beanie hats for a good cause. Scarlett teamed up with lifestyle label Neff to create Neff Hope which was created to raise awareness and funding for cancer research. She tells the mag:

"I helped create this Neff Beanie with the hope that every purchase might make a cancer patient feel a bit more comfortable during his/her treatments and look cool and be cozy all the while."

We love a sexy do-gooder!

Justin Bieber appeared on Late Night with David Letterman ... and had no problem joking about his paternity test. Mariah Yeater, who claimed Bieber fathered her son, had requested that JB take the test to prove he's the father.

Biebs and Letterman both referred to Yeater as a "weasel." He then went on to tell the host:

"I am 17, but it is going to happen….Being in the spotlight. I took it. They just swab your mouth."

Despite the negative press this accusation brought to the 17-year-old performer, seems as though he's managed to come out on top. Perhaps girlfriend Selena Gomez has kept his spirits bright throughout all the baby mama drama.

Looks like laughter is the best medicine!

Taking a day off from her strict gym routine, Nicole Richie dressed to impress as she indulged in a little retail therapy at Sunset Plaza in West Hollywood, on Tuesday.

The fashion designer is gearing up to celebrate her 1-year wedding anniversary with hubby Joel Madden on Dec. 11, but the pair have been relatively lax about making solid plans.

"Well his dream day is probably watching football and playing video games, and my dream day is watching Real Housewives, so maybe that will be our one-year [celebration]," Richie revealed to reporters during her House of Harlow 1960 holiday pop-up event at Fred Segal in L.A. "We'll do a game in the day and then Housewives at night."

How romantic!

Looks like someone needs a nap, and it's not little 3-year-old Bronx!

Proud papa Pete Wentz was out and about in Ventura with his son and a friend, but the singer looked absolutely exhausted as he carried the toddler to the car.

But apparently it's not lack of sleep that's got the Fall Out Boy down. Ashlee Simpson's ex Tweeted after being caught on camera looking forlorn: "nah not depressed, content. for some reason i come off sad when I'm happy and the reverse..."

Could've fooled us, Pete!

Now that former bad girl Angelina Jolie has pretty much settled down with partner Brad Pitt and their six kids, we sometimes forget the Oscar winner had such a naughty-girl streak.

In an exclusive interview airing Sunday on 60 Minutes, Jolie opens up on her wild child past, and how far she's come since those "darker" times.

The actresses confesses:

"I went through heavy, darker times and I survived them. I didn't die young, so I'm very lucky. There are other artists and people who didn't survive certain things."

Jolie chose not to go into specifics, adding:

"I think people can imagine that I did the most dangerous and I did the worst, and for many reasons I shouldn't be here. You think of those too many times where you came close to too many dangerous things, too many chances taken too far."

Now the international goodwill ambassador decides who gets to see her bad girl side, and when.

"I'm still a bad girl. I still have that side of me," Jolie exclaims. "It's just in its place now. ... It belongs to Brad."

After months of grueling practice and a soar ankle, J.R. Martinez's hard work has finally paid off!

Fan favorite Martinez and partner Karina Smirnoff became the latest winners to take home the coveted Mirror Ball trophy on Dancing with the Stars tonight.

The former U.S. Army soldier told reporters after his win:

“I just want to take a moment and breathe, take it in. The fact that we were able to top it off with this … we created a lot of magical moments together on this show that we’ll cherish for the rest of our lives. And my friend won her first mirror ball trophy! Everyone knows she is a beautiful dancer, but I’m able to vouch that she’s also a beautiful person. I’m glad I was able to see that and America was able to see that as well.”

Smirnoff added, “The journey is ending and I don’t want it to end because I don’t want to stop seeing him every single day in his Latin heels. That was the best part of the journey.”

Finishing at an impressive second place, Rob Kardashian ended his DWTS career with an impressive 57 points.

“I could not have asked for a better ending. We ended with a perfect score [on Monday] and I had an awesome experience with Cheryl, I literally shocked myself week after week and still, even tonight, we improved. I am super happy with the whole outcome of everything. I shocked myself that I was in the final two,” the reality star gushed after the show.

Ricki Lake was the first contestant to be voted off tonight, and the former TV show host made sure to thank fans for all of their support. "I really appreciate everyone who voted for me and supported me along the way. This is a fantasy come true," Lake expressed.

So what's next for Martinez? The war vet will serve as Grand Marshall for the 2012 Rose Parade on New Years Day this year.

A very pregnant Jessica Simpson is heading to Texas for a big family reunion!

The 31-year-old mama-to-be arrived at LAX in a long, striped fuzzy coat and snug black top. Jess has to keep that baby bump warm, ya'll! We're lovin' the orange heels and Birkin.

With fiance Eric Johnson by her side, Ms. Simpson looked happy as ever to be heading out of town for Thanksgiving. Good thing she's going now because once her third trimester begins, she'll no longer be able to fly due to being so far along in her pregnancy.

The expecting singer has a lot to be thankful for ... new baby, new soon-to-be hubby and new in-laws. Let's hope she has a blast at the reunion!

Stay safe, Jess!

Well, maybe she's NOT dancing for you, but she's giving us all a sneak peek at her upcoming video for the single "Dance For You" from her latest album 4.

The now pregnant songstress, dancing in skimpy lingerie in a '40s film noir setting, is certainly showing no signs of a baby bump in this clip.

Looks like Jay-Z's 30-year-old wifey was busy filming numerous videos before getting pregnant. First she shot the video for "Love On Top," then "Party" and now this one.

The full-length video will be featured on the deluxe edition of Beyonce's "Live at Roseland" DVD. No one can say this mama-to-be isn't a hard worker.
