Believe it or not, Jessica Biel turns 31 today! The starlet is at the forefront of fashion with designers lining up to style the sporty and chic actress who doesn't look a day over 25.

When we took a look back at Biel's tenure in the spotlight, we couldn't help but notice a few years in the 90's we're pretty sure she'd like to forget. Back during her "7th Heaven" days, the young actress was known for her tan lines and tube tops, finishing off the outfit with a pair of platform sandals and an ankle bracelet.

But Jessica quickly transformed in the 2000's into the fashion icon she is today, while keeping her effortless style in tact. From designer Giambattista Valli, who is rumored to have designed Biel's wedding dress, to Zac Posen, Jessica constantly surprises us. We cannot wait to see what else she has in store, because whatever it may be, we know she will hit the mark!
