A plastic surgeon comments on her disastrous appearance at the VMAs:
Ms. Spears doesn’t look in fact look “bad”, she looks normal after having 2 children in rapid succession. Unfortunately, normal people aren’t the benchmark for her field of work, and she did herself no favors wearing an outfit accentuating her body’s changes.
She’s got a modest “mommy tummy” which is relaxation of her muscles and fascia of the abdominal wall you get from pregnancy, weight gain/loss, and normal aging. The younger you are and the less weight you gain when you get pregnant, the less of this you tend to see.
