Pussycat Dolls are tired of "being sisters 24 hours a day" and taking a break from music.

Singer Melody Thornton has denied the girl group - also consisting of Nicole Scherzinger, Ashley Roberts, Kimberly Wyatt and Jessica Sutta - are splitting for good, but admits they need a rest from each other.

Pussycat Dolls star Jessica Sutta is dating the group's manager. The sexy singer has reportedly been romancing Jeff Haddad for just over a month, but the pair have been trying to keep the fledgling relationship a secret while it's still in its early stages.

A source said: "Jeff is not your usual manager. He's not dull, he's in his 30s, is cool and is very good looking. Things between him and Jessica just developed naturally but they seem to be smitten with each other."

Nicole Scherzinger has made an internet tribute to her boyfriend Lewis Hamilton.

The Pussycat Dolls singer speaks tenderly about the 23-year-old racing driver - who became the youngest Formula One world champion in history after winning the Brazilian Grand Prix on Sunday - in the 40 second clip, and encouraged her fans to learn about his sport.

The Pussycat Dolls visit a "love guru" for hugs when they are feeling depressed.

The group revealed when their daily regime of personal appearances, parties, performances and recording gets too much they take a trip to their "love guru" - a humanitarian and spiritualist from South India - who cuddles them until they feel better. They are also firm believers in karma and reincarnation, and feel they are bound together spiritually.
