At the party thrown at Shah Rukh Khan's Mannat, Hollywood star Gerard Butler left all the Bollywood celebs present at the bash mighty impressed. It is learnt from our sources present at the party that he was there partying hard right till 6 am in the morning.

Revealed our source, "Gerald showed amazing sense of humour and intelligence while interacting with the star celebs present at the party.

His behaviour was very down to earth and it was a learning lesson for a quiet a few snobby Bollywood celebs who prefer who at general Bollywood parties always tend to keep their nose up in the air despite not much talent or hits to talk about."

Another source adds, "Gerald is visiting Mumbai for the first time and plans to head to Hrishikesh, and then return to Mumbai to board their flight back to Mumbai. He has also been enjoying dinner at chic Mumbai restaurants such as Indigo and the Thai Pavilion."

The Mannat bash was actually hosted by SRK's wife Gauri along with socialite Kaajal Anand. Amongst the guests present at the party were the King Khan's close group of friends such as Arjun Rampal and his wife Mehr Jesia, who live close by to SRK's villa, Farhan Akhtar and wife Adhuna (who also live within walking distance), Karan Johar, Dino Morea, Sajid Khan, Ashustosh Gowariker, Seema (Sohail) Khan, Malaika Arora Khan and Amrita Arora. Aamir Khan's nephew Imran Khan with his girlfriend Avantika were the surprise guest.

One can recollect, SRK and Gauri met Butler least year in Dubai at the launch of Atlantis, The Palm, and stayed in touch. At the time the actor mentioned planning a back-packing trip to India with his friends.
