In Touch Weekly claims that the 29-year-old singer-turned-fashion designer is pregnant, and that she was so shocked by the results of test number one that she did nine more.
'When the first test came back positive, she called a close friend and asked her to buy several more tests and rush them over,' said a source. 'Now, she's the happiest she's ever been.'
Her fiancé Eric Johnson, who she is set to marry in November, is said to be equally thrilled.
'He told her he wasn't happy — he was ecstatic beyond words,' added the insider.
