Almost 30 years have passed since actress Natalie Wood died of an apparent drowning in the Pacific Ocean near Catalina Island, and now The Los Angeles County Sheriff's have reopened the case. The actress and husband Robert Wagner had been on a yacht called the Splendour back in 1981 ... with fellow actor Christopher Walken.

Homicide investigators are working with Dennis Davern, the former captain of the Splendour who talked about the night Natalie went missing in the 2009 book, Goodbye Natalie, Goodbye Splendour. Davern co-wrote the book with his friend Marti Rulli. The captain says he believes the actress' death was a result of a fight with Wagner.

Investigators say they have "additional information" in the case and they'll reveal what they have at an 11am press conference this morning.

Various reports claim that the story surrounding Wood's death was a cover-up and Wagner may have been to blame. In September 2009, Wagner wrote in his book "Pieces of My Heart" that he was jealous of Wood's chemistry with Walken and that the night of her death, the couple had a fight.

Wood's body was found floating in the ocean and she was wearing a long nightgown, socks and a jacket. According to the autopsy report, she had two dozen bruises on her body and a cut on her left cheek.

In his book, Wagner admits he had an argument with Walken ... and Wood, who was present with the two men, went back to their room. However, after cooling things off with Walken, Wagner says he returned to his room to find Natalie missing.

Wagner's publicist said that the actor's family will "fully support the efforts of the LA County Sheriff's Department and trust they will evaluate whether any new information relating to the death of Natalie Wood Wagner is valid, and that it comes from a credible source or sources other than those simply trying to profit from the 30 year anniversary of her tragic death."

Wood and Wagner were married in 1957, but then split in 1962. The couple remarried in 1972. Wood and Walken were starring together in the movie Brainstorm.

Justin Bieber knows he's not the baby daddy and he's ready and willing to prove it!

The "Baby" singer will move forward with submitting a DNA test to settle claims that he is the father of Mariah Yeater's four-month-old son, who was allegedly conceived in a bathroom after one of Bieber's concerts.

In a recent radio interview with Elvis Duran, Biebs confessed:

"As far as the whole 'baby' situation, it's unfortunate that it had to happen like that, you know, people make false accusations but things happen in this industry and you just have to keep your head high and be positive. If it was up to me, it would've been a better story—like Justin Bieber went off to South America with this 27-year-old supermodel. That would've been an awesome rumor."

While Yeater filed a motion to dismiss her paternity action on Nov. 9 after damming text messages came to light, Bieber's camp still wants to move forward with the paternity test.

The 17-year-old's publicist told E! News on Thursday that he will take the test to put the matter to rest, and hold "those involved with bringing this suit accountable for their actions."

The entertainer's attorney, Howard Weitzman, added:

"Our independent investigation indicates Ms. Yeater never met Justin, she has consistently identified another man as the child's father, and Ms. Yeater and her co-conspirators hatched this scheme in order to extort money from him and to sell her story to the media. There have been no settlement discussions and there never will be."

Sounds like Yeater's story is starting to unravel!

Looks like the ring is finally off!

It was back to work as usual for Ashton Kutcher, who enjoyed a cigarette during a break from filming Two and a Half Men, just hours after Demi Moore announced plans to divorce.

The news came as a surprise to some, because Moore seemed to have forgiven Kutcher for his infidelities, and both had kept their wedding rings firmly in place.

But the G.I. Jane star let the world know it was officially over when she said in a statement on Thursday, "As a woman, a mother and a wife, there are certain values and vows that I hold sacred, and it is in this spirit that I have chosen to move forward with my life."

Kutcher replied with the Tweet: "I will forever cherish the time I spent with Demi. Marriage is one of the most difficult things in the world and unfortunately sometimes they fail. Love and Light, AK."

Moore is now meeting with her lawyers to begin dividing up their estimated $290 million fortune.

Sexy songstress Rihanna made an exclusive appearance on ‘The Ellen DeGeneres Show”, and she dished on everything from hating her single status to the well-being of her lady parts!

Rihanna on being single…

"I’m not necessarily happy being single. It’s not really that cool. It sucks but it is, what it is. Let me say this right, because I don’t want to make it seem like, my work is my everything. I do put a lot into my job. Most of my time if not all of it. It definitely affects my personal life. My personal life is pretty much non-existent. Which is not good, not for the long run. Not for me, not for “Her” (points to in-between her legs) It's not fun."

And what is Esquire mag's "Sexist Woman Alive" looking for in a man?

"I like men that are more aggressive but mysterious but I like a man to be very sure. I like them to be sure of them selves and know that you’re the man. I’m the lady and the only way for us to make this work is for us to play our roles. You know, I can’t really be the man for you. I don’t want to have to be. I’m the man at work all the time."

The "S&M" singer added, "That’s why I stay on Twitter a lot. So I can conversate with my fans. Because I don’t get any booty calls."

Check out Riri's full interview on The Ellen DeGeneres Show premiering Monday, November 21!

It was boys-only at the Breaking Dawn Part 1 premier in Barcelona Thursday night, but no one seemed to mind showering Taylor Lautner and Robert Pattinson with all the attention!

Breaking the hearts of Twihards everywhere, the world's most famous vampire recently admitted that he would actually "hate" Twilight if he wasn't in it.

“The people who don't like it are generally the people who haven't seen it. They're like all judgmental and stuff. Cynical people. But I think I am a judgmental and cynical person, who would just hate it without having seen anything. I just think I'm a bad person."

What would Stephanie Meyer say?

Hmm, we know Megan Fox has a thing for baggy shirts, but it also looks like she's trying to hide something here!

The 25-year-old starlet was spotted running errands in Los Angeles, and is it just us, or does she appear to be sporting a baby bump?! We reached out to Megan's rep about the photos, but have yet to hear back. Think she has a bun in the oven, or did she simply snarf down a bunch of carbs at lunch today?

UPDATE: Megan's rep tells X17online that the starlet isn't expecting. Looks like it's just a funny angle -- and maybe a big lunch!

Despite the fact that there are reports of Samantha Ronson and former lady love Lindsay Lohan rekindling their romance, we spotted the DJ and her girlfriend Erin Foster playing with an unidentified (and adorable!) baby at a park in Los Angeles today.

We never would have guessed this, but SamRo was a natural with the tiny tot! And at 34, she's not exactly a spring chicken, so is it possible that the "Built This Way" singer has babies on the brain?

Jessica Alba and her daughter Honor were spotted at a nail salon in Beverly Hills on Wednesday, and the ladies were pampered with manicures and pedicures. Jess went with a festive red, and Honor eagerly showed off her blue and pink paint job. Too cute!
