Christina Aguilera reportedly fired key members of her entourage after throwing a massive tantrum.

The 'Dirrty' singer allegedly dispensed with her day-to-day manager, one of her assistants and her publicity firm BWR after poor sales of the People magazine featuring pictures of her and her new five-week old son Max Liron left her fuming.

People magazine paid a reported $1.5 million for pictures of Christina with her new baby, but the issue is believed to have sold just 1.3 million copies, about 100,000 less than average.

When Christina was told of the poor sales she "went crazy" and took the drastic action, according to the New York Daily News newspaper.

Meanwhile, Jennifer Lopez and husband Marc Anthony have reportedly agreed a $6 million deal with People for exclusive pictures of their twins, who were born on Friday.

The magazine will also reveal the names the couple have chosen for their children. BWR, who also represent Jennifer, are not thought to have been involved in the deal.
