Biker darling! Kylie Jenner wears scanty lingerie for sizzling bike photograph shoot... as her twentieth birthday festivity proceeds

She marked her birthday on Thursday with a steamy red-tinged lingerie shoot.

What's more, it appears Kylie Jenner wasn't finished celebrating, as she posted some more hot snaps on Instagram later in the day.

The recently stamped 20-year-old kept the gathering running with two shots of her hanging out with a pink bike.

    The reality starlet showed off her famous curves in a pink bra and panty set.

A sheer crop top featured numerous sparkles and floral elements, and included fluffy pompoms attached to the wrists.

Some massively tall peep-toe platform heels made the saucy number even edgier.

Her pink-tinged wavy tresses were parted on the left and fell down past her ample bust.

Of course the Lip Kit mogul's make-up was flawless.

In addition to posing in front of the vehicle, the youngest Jenner took the opportunity to provocatively straddle the vintage machine for a different shot.

Meanwhile, Kylie's birthday seems to be quite an action packed affair, as even her driving on a local California freeway escalated into a scene

The birthday girl somehow managed to warrant a police escort as she drove along in her eye-catching orange Lamborghini.

Though it wasn't clear what necessitated the attention from law enforcement, she eventually exited the freeway safely.

Later, the social media darling toned things down a bit, as she decided to stop in for to enjoy a movie with sister Khloe
