Mariah Carey shares bond with trainer

Mariah Carey's trainer has become one of her "closest confidantes".

The American singer and her husband Nick Cannon welcomed twins into the world in April. After their birth Mariah was keen to get back in shape, so enlisted the help of trainer Bernardo Coppola.

The two get along famously, and have struck up a solid friendship.

"It was a rough time for Mariah after her twins were born, because she lost a lot of independence and had packed on the pounds during the pregnancy," a source told National Enquirer.

"Then Bernardo came along. He helped Mariah get her confidence back about her looks and body. He quickly became one of her closest confidantes."

Together the pair have drawn up a diet and exercise regime for Mariah. She is now working out daily and watching what she eats, with the pair even spending time together once their exercise is done.

Mariah will be debuting her new figure on the 20/20 show on October 21, when she will introduce her son Moroccan Scott and daughter Monroe to fans.
