According to UK site Female First, Scherzinger has lots on her plate from trying to finish her album to trying to pressure her longtime boyfriend Lewis Hamilton to marry her.

The source said Sunday, "Nicole's really feeling the pressure - she's determined to make her new album and is spending countless hours promoting it. At the same time, she has to travel back and forth to see Lewis in Monaco and she's been pushing for a wedding so they can start a family together.

"She's confided in friends that she felt ill and trapped in the car - she says she had to get out of the limo and didn't care if it was still moving. She's so busy with work, she says she doesn't have time to sort everything out. She feels so lost right now."

News of Scherzinger's sudden movement hit the Internet last week. Reports say that she felt nauseous while in the back seat of the car as she headed back to her hotel in London. She demanded the driver pull over but when they would not because of busy traffic she took matters into her own hands and jumped out. In the end, she caused a crash during rush-hour.

The driver ended up leaving the car in drive when he tried to rescue Scherzinger. The car rear-ended a separate one.

Scherzinger is in London to tape her music video for her brand new song Run. It takes place along the Victoria Embankment.
