Pink lost her baby weight through "sheer blood, sweat and tears".
The songstress gave birth to daughter Willow in June last year. Since welcoming her new family addition, Pink has got back into impressive shape, and insiders close to the star say her new body is the result of total determination.
"Pink lost 49lb in baby weight through sheer blood, sweat and tears. She did an hour of hard core cardio every day," a source told British magazine Heat.
Pink confidently showed off the results of her hard work in a cut-out black dress last week when she was announced as the new face of CoverGirl.
The source added that Pink is modest about her enviable frame.
"She downplays how hard she had to work for it, because she doesn't like to brag, but she put a huge effort in and she feels amazing," the insider explained.
Pink admitted that she indulged during her pregnancy, jokingly revealing: "I think my baby may be part cheesecake" because of her sweet tooth.© Cover Media
