Kate Hudson used to be a stalker. The "Bride Wars" actress - who has a four-year-old son Ryder with ex-husband Chris Robinson - admits she went through a phase of obsessively following her potential conquests.

She said: "I don't like being smothered. If a guy is calling me all the time, it just seems so desperate. Although I did turn into a stalker once."

Kate Hudson struggles to find a man because her tastes are so similar to other women's.

The 'Fool's Gold' star - who is divorced from Chris Robinson and has been romantically linked to actor Owen Wilson and cyclist Lance Armstrong in the past - believes she is still single because women always look for the same characteristics in men, so end up competing for the affections of potential partners.

Oprah Winfrey is the most generous celebrity in the world. The humanitarian talk show host topped a list compiled by Parade magazine, after donating a staggering $50.2 million to various charities in the last year.

As well as her huge donations, Oprah is the founder of Oprah's Angel Network - which helps underprivileged women and children worldwide.
