She had a reduction in 2010 so she her present bosom may not match that mesmerizing profile photo. Gigantomastia is a condition that causes female boobs to keep growing.

Salma Hayek noted that she suffers from gigantomastia but the condition could boost a woman's career if she can avoid the health issues.
