One of the blondes, named Shell Maci according to her Twitter page, posted numerous photos to the social networking site as she and her friend snooped around the apartment, with Kim Kardashian notably absent.
As well as taking plenty of snaps the girls filmed two short videos.
In one a girl looks into the camera with Kris Humphries stood behind but her it appears that he was actually being filmed by a TV camera, which can be seen in the far right side of the shot.
Whether they were the E! reality cameras have not been confirmed but were also in the room, sparking speculation it may have been a manufactured publicity stunt.
The blonde girls are seen them holding up the KK branded towels and Kris Humphries is seen clearly in the background.
As the girls film Kris Humphries appears oblivious to the face he has been caught on camera entertaining in the New York hotel suite.
As well as posing on Kris Humphries and Kim Kardashian’s bed the girls were also seen exploring the reality star’s closet as well as climbing into their bathtub.
While filming in the bathroom Kris Humphries can be seen walking past the doorway indicating he didn’t mind the ladies exploring the apartment.
The girls appeared excited an animated by their experience inside the couple’s plush New York pad, where they were filming Kourtney and Kim Take New York.
To prove they were in Kris Humphries and Kim Kardashian’s apartment, the girls were seen holding up the couple’s towels with the KK and KH initials embroidery on them.
It is not clear if they stayed the night or simply enjoyed the party but Shell Maci tweeted: “omggggg crazy night last night.”
Kourtney and Kim Take New York is currently airing on E! depicting the couple’s enjoying time together as newlyweds and Sunday’s episode saw the couple agree to try for a baby.
But by the end of the episode it became clear they were on very different pages and Kim Kardashian had changed her mind about trying for a child with Kris Humphries.
Kim Kardashian famously filed for divorce from Kris Humphries on October 31, after just 72 days of marriage.
Kris Humphries is now seeking an annulment and last week he gave an awkward interview on Good Morning America, where he deflected questions about his estranged wife.
