Hints:

1) It's NOT Miley Cyrus.

Brittany Murphy's father, Angelo Bertolotti, is suing the Los Angeles County Coroner's Office because he claims her autopsy was "never fully investigated.”

Bertolotti, who is also suing the Los Angeles Police Department, has requested samples of his daughter’s hair for his own testing. “I’m not going to rest until my daughter’s untimely demise is properly investigated, which hasn’t happened so far. Her case deserves more than a superficial glance,” Bertolotti said in a press release.

In 2009 the coroner’s office ruled that the 32-year-old actress died of pneumonia, anemia and prescription drug intoxication, but Bertolotti believes toxic mold in her Hollywood Hills home could have caused her death, according to The Hollywood Reporter.

Sinead O'Connor is going public with yet another personal issue.

The "Nothing Compares 2 U" singer, who reportedly attempted suicide recently, is reaching out to her Twitter followers for support. The 45-year-old singer Tweeted:

"Does anyone know a psychiatrist in Dublin or Wicklow who could urgently see me today please? I'm really unwell and in danger. I desperately need to get back on meds today."

Sinead was hospitalized after suffering a broken ankle, and according to reports, tried to end her life.

Last September, the singer wrote on her website, "Anyway...If any1 knows how I can kill myself...Without my kids finding out I did it deliberately pls tell me asa f--kin p."

O'Connor recently told the U.K. Sun, "God obviously wants me around —- though I can't think why."

Kim Kardashian isn't staying quiet regarding claims that Khloe is not the daughter of Robert Kardashian.

When asked if she's bothered by the rumors that she calls "completely not true," the 31-year-old reality star tells an X17 photographer:

"Not really. Not coming from someone that was married to my dad once for two months and one for a couple of weeks."

Kim is referring to her late father's ex wives ... Ellen Kardashian, 63, who married Robert in 2003 for only two months and Jan Ashley, who gave an explosive interview to Star.

Ashley told the mag, "He just kind of looked at me and said (it) like it was a matter of fact. He said, 'Well, you know that Khloe's not really a Kardashian, don't you?' And I said ...'Okay,' and that was it."

Ellen went on to say, "Robert did question the fact that Khloe was his. Any normal man would if they knew their wife had cheated on him." Robert's ex also stated that she was told by the late attorney that "his marriage was sexless at the time Khloe was conceived."

Rihanna sat courtside at the Los Angeles Clippers game last night, and she seemed absolutely thrilled when the boys beat the Miami Heat 95-89. The game went into overtime, and Twitter was blowing up with posts about the team. Is it possible that the Clippers will beat the Lake show AGAIN when they play them this weekend?

Days after Jay-Z and Beyonce's little girl Blue Ivy was born, her dad turned her cries into a hit song. "Glory", featuring baby Blue, hit the web and features the rapper talking about "the most amazing feeling."

The rap lullaby is expected to hit the Billboard charts at #74. Billboard's editorial director Bill Werde tells the NY Daily News:

"It's historical. The charts are almost 72 years old, so to be the youngest ever to chart is something."

With such superstar parents, we have a feeling this little girl has a great future on the charts!

Listen to "Glory" below.

Lindsay Lohan attended the Weinstein Company and Audi party at the Chateau Marmont last night, and even though she had a rough 2011, it looks like this could really be the year. Not only is she lining up all sorts of new gigs, but she's focused on her sobriety and she's looking better than ever! While this dark dress is on the conservative side for Lilo (what, no plunging neckline?!), we're not complaining -- we're still getting a peek at her sexy curves!

Bradley Cooper and Michelle Williams also attended the event, and while Lindsay may have been laying off the sauce, it looks like Bradley definitely enjoyed the complimentary cocktails!

Robert Pattinson hit the stage at the People's Choice Awards at the Nokia Live Theatre with a much shorter 'do. No matter what hairstyle he chooses, the Twilight hottie is insanely gorgeous!

Pattinson, 25, looked casual in denim and a blue polo shirt while accepting his award for Favorite Drama Movie for Water for Elephants.

Thoughts on Rob's buzz?
