(Cover) - EN Showbiz - Justin Bieber has reportedly spent $1 million on girlfriend Selena Gomez.

The pair have only been dating for a few months but Justin has already splashed out a sizeable sum on the 19-year-old performer.

In Touch magazine has claimed that friends are concerned that the teen star might be running through his fortune in a desperate bid to impress his lady love.

"She is his dream girl," a friend of the 17-year-old said. "He really wants to impress her."

Justin is said to have already amassed a $100 million fortune through his hit songs, tours and merchandise deals.

But the insider said Justin has to go all out each time he and Selena have a date. The pair very rarely go on a regular movie and popcorn night.

"Every date is a production," the source said. "From bodyguards to flowers, private jets to catered meals.

"Plus he buys her major gifts. It's all adding up pretty quickly."

Last month Justin hired out the whole of the Staples Center in Los Angeles just so he could have an intimate dinner with Selena and the pair later watched Titanic on the stadium's giant screen. (C) Cover Media
