Justin Bieber ''only had eyes for'' British reality TV star Lauren Pope at his wild party this weekend.

The 18-year-old singer threw a huge bash - which prompted visits from police amid complaints of excessive noise - at his Los Angeles home on Friday (15.11.13) night and though there were over 100 guests in attendance, he reportedly spent most of the evening with the former glamour model, who is best known for appearing on 'The Only Way is Essex'.

A source told The Sun newspaper: ''They were together all night and seemed to only have eyes for each other.

''They were dancing and talking and seemed pretty into one another.

''Lauren was accompanied by her friend Donatella Panayiotou, who is in LA filming a new reality TV show for E!.''

Lauren was one of a number of guests who stayed on at the party after it was shut down by police at around 1am.

However, it is unlikely the 30-year-old blonde beauty will be telling fans about her night at the 'Believe' star's home as it has been revealed all guests were asked to sign a confidentiality agreement before they were allowed entry.

According to TMZ - who obtained a copy of the agreement - guests and workers were prohibited from making posts on Twitter or Facebook, texting or using phones during the event or discussing in any way what went on behind the closed doors of his Calabasas mansion.

The document stipulated that anyone breaking the rules was liable to pay up the hefty sum with no exceptions, although Justin has reduced the fee from $5 million to $3 million according to a contract found for one of his previous parties.

Other guests at the party included Snoop Lion, T.I., and Chris Brown.
