Pete Wentz is convinced he is going to be murdered.

The Fall Out Boy star is so paranoid his life is going to be taken, he won't open his front door in case someone is there waiting to kill him.

Pete - who attempted suicide in 2005 - said: "I refuse to answer my front door because I'm convinced someone is going to murder me.

The 24-year-old singer - who gave birth to Bronx Mowgli, her first child with husband Pete Wentz, in November - is determined to ditch her baby weight, and so has embarked on a "mommy and me" workout.

Ashlee - who has already lost half of the 30 lbs she is aiming to shed - is following Jackie Keller's 30-day Body After Baby plan, meaning she is completing low-impact exercise such as playing peek-a-boo with Bronx.

Ashlee Simpson has blasted critics who attacked her sister Jessica's figure. The 24-year-old singer has defended her older sibling - who was photographed wearing unflattering high-waisted jeans at a recent Florida concert with a seemingly fuller figure - insisting the comments about Jessica's weight are "embarrassing and belittling."

She wrote on her blog: "I am completely disgusted. Since when did a woman's weight become newsworthy? How can we expect teenage girls to love and respect themselves in an environment where we criticize a size two figure?"

Beyonce Knowles reportedly refused to walk to her car in the cold after rehearsing for U.S. President Barack Obama's pre-inauguration concert.

The "If I Were A Boy" singer was furious when she was told she would have to make her own way to her car four blocks away as the surrounding streets had been shut amid heightened security before the event.

Jennifer Lopez was star struck when she met U.S. President-elect Barack Obama. The singer-and-actress attended the Latino Inaugural Gala in Washington, D.C. on Sunday evening and admitted Obama was the only person she was interested in meeting.

She said: "He is the biggest star here, even though it's chock-full of celebrities. The night he won the election, you could feel it in the air. I was watching him with tears in my eyes, thinking, 'Yes. Something is different. Something is happening.' We're very excited."
