Katy Perry's sister saved her from rehab. The "Hot N Cold" singer is always accompanied by elder sibling Angela, 26, and says her sister's harsh stance has stopped her spiraling out of control.

She said: "Angela is the one who kicks my a*s. The way she wakes me up is pretty horrible. She'll stand over my face with a glass of cold water and count to three. If I'm not up by three, she'll pour."

Katy Perry loves wearing romper suits. The "I Kissed A Girl" singer is a huge fan of the all-in-one garments - which are usually worn by babies - and often dons one when she is relaxing in private.

She said: "At home, I sit around in a zebra-print romper suit from H+M. Rompers are very me. They're super easy to run around in. With anything you wear, it's about having confidence."

Megan Fox has been named the world's second-most "drooled over woman." The "Transformers" actress came second in Maxim magazine's 2009 Hot 100, an annual poll to find the world's most desirable women.

Maxim wrote: "Seriously, do women get more painfully hot than this? Megan Fox has the face of an angel, a body so perfect that God may have carved it out of soap and sex appeal that could melt a unicorn's horn. Plus, we hear she smells like clouds."

Katy Perry wants to marry an older man. The 24-year-old singer - who recently reunited with Gym Class Heroes singer Travis McCoy following a brief split - hates being single and can see herself settling down with someone who has more life experience.

She said: "I don't like being single. I live a fantastic life, full of magical things, and at the end of the day all I want to do is share it with someone."

Katy Perry wears her grandmother's clothes. The "I Kissed A Girl" singer has no qualms about wearing items from her elderly relative's wardrobe, insisting she will don anything if she thinks it suits her.

She said: "It doesn't matter who makes it, where it comes from, whether it's your grandmother's closet or it's a couture showroom. If it looks good on you, wear it!"
