In the early 2000s, Mary-Kate and Ashley Olsen were the most famous teenagers in the world.
The now 34-year-old twins, who were born in Los Angeles in 1986, launched to fame when they made their acting debut on American sitcom Full House at just six months old.
From 1987, the fraternal twins shared the role of Michelle Tanner for the entire run of the series, sharing their first steps and first words on set.

It was a role that solidified Mary-Kate and Ashley Olsen's place in pop culture, changing the lives of their entire family.
In fact, their siblings, older brother Trent and younger sister Elizabeth, virtually grew up on sets.
"It was just normal. It was never weird," Elizabeth Olsen told Danny Pellegrino on his podcast, Everything Iconic.
"When my brother and I would get picked up from school, that was our after-school care," she added, speaking to SFGate.
"It was really hanging around on set, so every once in a while, they'd ask us, 'So, do you guys want to be in this one? We'll put gum in your hair.' To me, it was never acting. It was silly and fun."
