(Cover) - EN Showbiz - Mariah Carey is having her baby shower this weekend.

The singing superstar is currently pregnant with twins, her first children with husband Nick Cannon. Mariah recently revealed she is expecting a boy and a girl and she is due to give birth this spring.

To prepare for the new arrivals, the stars publicist Cindy Berger and manager Louise McNally are planning to throw her a lavish party in Beverly Hills on Sunday afternoon. The pair have booked a private area in the Beverly Hills Hotel and are believed to have decided to give the party a blue and pink theme.

Details about the baby gift registry Mariah and Nick set up have reportedly been leaked by website TooFab.com. It has been claimed the couple have requested items including a $1,2000 toy giraffe and a $2,000 customised bedding set.

The 40-year-old singer has kept a low-profile during her pregnancy and refused to confirm she was having a baby for several months. Mariah admits she was reluctant to reveal she was expecting a boy and a girl because she wanted to keep the news low-key.

"Even before we announced it was twins, I was trying to keep everything genderneutral because I didn't want to impose an identity on them too soon," she said recently. (C) Cover Media
