Zac Efron #21 – Jen Selter
The term ‘Instagram celebrity’ was practically penned for Jen Selter. Indeed, her celebrity status is almost entirely down to how incredible she looks in yoga pants.
Jen is a fitness model whose impressive butt has girls the world over green with envy, and drives guys crazy with lust. She has even been credited with being a driving force behind (pun intended!) the recent craze for yoga pants, squatting and big butts in general.
