Well, just days after separating from her Swedish boyfriend, Paris Hilton has stripped to her underwear but this time for a new German advertisement.

In a video posted on 'youtube' portal, the 26-year-old hotel heiress is seen lounging in bed in tiny yellow knickers for 'GoYellow.de'.

In the 30-second clip, she is also seen biting into an apple and adjusting her knickers before being called to the door for a dougnut delivery.
