Guilty Pleasure: Caitlyn Jenner Smokes Cigarette Outside Her Porsche -- Hides Face In Shame!

RadarOnline.com previously reported that Caitlyn Jenner's friends were begging her to stop smoking to preserve her health -- but it appears that the advice went in one ear and out the other!

Caitlyn checked her phone in the front seat of her parked car.

But she hid her face from the paparazzi with an envelope for her son Bart.

She puffed on cigarettes outside her Porsche...

Even though people who care about her have urged her to stop!

She kept her chin up after enjoying her smoke.

Her lipgloss appeared un-disturbed.

Done with the smokes, she got back in her car.
