The 31-year-old mother of two, who has donned them on-screen - most famously in 2003 film 'Honey', said she is ditching the style once and for all, reported Sun online.
"I probably won't ever wear booty shorts. I feel pretty confident about that," Alba said.
The 'Sin City' star is also unwilling to go back to one aspect of 80s power dressing.
"And I don't like oversize shoulder pads," she added.
When discussing her relationship with her husband, the producer Cash Warren, she said she did not realise he was "the one" right away.
"I didn't know he was 'the one' but as soon as I met him I just knew we would know each other forever," she said.
