Justin Bieber, who is in the midst of his Never Say Never World Tour, is used to young female fans swarming his hotel and the places he goes on a daily basis. On a recent stop in Liverpool, England, two of Biebs' fans took it one step too far.

According to UK's Daily Mirror, two teenage girls got past the massive crowds and into the Hard Days and Night Hotel where Bieber was staying. The girls reportedly stole housekeeping outfits and proceeded to the singer's room. Upon knocking on Bieber's door, calling "housekeeping," the two entered the suite, which was vacant at the time.

"Having been allowed in, the girls began half-heartedly polishing tables and dusting surfaces," a source tells the London-based newspaper.

Once alone in the room, the fans began taking photos of the singer's belongings, and they even tried getting into his bed. The source says that the giggling eventually gave their cover away when a member of Bieber's security team heard them from the next room.

A hotel spokeswoman insisted she had no knowledge of the incident, saying: "There was a strong police presence outside not letting in members of the public, plus we employed an extra 20 security personnel."

Bieber's tour continues tomorrow night in London at the O2 Arena. For a complete list of tour dates where Bieber will be performing, click here.
