Shakira is desperate to "reproduce." The "Beautiful Liar" singer is certain her fiance Antonio de la Rua - the son of Argentina's former president Fernando de La Rua - is the "right person" to start a family with, and is planning to start trying for a baby as soon as possible.

The 32-year-old star said: "I constantly think about raising a family. I want to reproduce so bad! Antonio and I have been together for nine years and function as a married couple even though we're not married."

Beyonce Knowles has hinted she may get pregnant when she finishes her current world tour.

The 'Crazy in Love' singer - who married rapper Jay-Z in a secret ceremony last April - hasn't got time to start a family now but insists she does want to become a mother.

Madonna had her phone confiscated at Jennifer Lopez's 40th birthday party. The singer and other celebrity guests, including Rihanna, Beyonce Knowles, Alicia Keys and Mary J Blige, were forced to hand over their mobile phones and any cameras before they were allowed into New York's Hotel Griffou to celebrate with Jennifer last Friday.

The strict rules angered some partygoers, but Madonna and Rihanna reportedly used the increased privacy to dance "exuberantly" to Rob Base and DJ EZ's hit "It Takes Two."

Jay-Z and Rihanna racked up a $12,000 bar bill during a night out. The "99 Problems" rapper and the "Umbrella" singer - who is signed to his record label Def Jam Recordings - partied with friends in the VIP lounge at London club Vendome, in the U.K. city's exclusive Chelsea district, on Tuesday night.

Jay-Z - who is married to "Crazy in Love" singer Beyonce Knowles - ensured their entourages enjoyed the evening by ordering countless bottles of expensive champagne and vodka.

Solange Knowles hates the way she looks when she sings. The 23-year-old singer - sister of "Halo" star Beyonce - stopped halfway through her performance at the Essence Music Festival in New Orleans last weekend and demanded a paparazzo stop taking photos of her.

As the audience looked on in amazement, Solange shouted: "Mr. Photographer, you are making me self-conscious. I swear I make the same stupid three faces over and over again, so please leave me be."
