If there’s one thing about Kendall Jenner — she’s always Jenner-ous with the heat! And what better excuse to scroll through the archives than her big 3-0?

Check out the gallery — ’cause it looks like Kendall’s been in her dirty-30-flirty era long before the candles hit the cake … showing off that supermodel physique in the tiniest of bikinis!

Of course, Kendall’s got posing down to an art … swapping catwalks for coastlines and serving looks while soaking up the sun in every jet-set spot imaginable.
