BRITNEY SPEARS - BRITNEY'S J.LO POSE

Pop princess BRITNEY SPEARS is so excited to be working with JENNIFER LOPEZ, she's already started to model herself on the curvy Latina.

Skinny Spears is said to be joining J.LO and pop goddess MADONNA for a superstar collaboration at the MTV VIDEO MUSIC AWARDS next week (28AUG03). The trio met up for a girly lunch at Madonna's home to celebrate her 45th birthday on Saturday (16AUG03), and allegedly to discuss their show.

And youngster Britney has been so impressed by J.Lo's famous shape, she was spotted mimicking it - by shoving out her bottom in imitation of the stunning star.

An onlooker laughs, "Britney was just larking around and decided to stick her bottom out as J.Lo tends to do more naturally. The pair have spent some time together before they perform at the awards ceremony and J.Lo's backside has clearly made something of an impression on her."

Despite their best efforts, the A-list trio were unable to keep their plans under wraps.

A source close to Madonna says, "It should be incredible. People couldn't understand why Britney and Jennifer went to Madonna's birthday party but now it all makes sense.

"The thought of those three on stage together will send shivers down most people's spines. It is going to be a sight to behold. Keeping it a secret was always going to be very difficult."
