It was a pleasant surprise for the actors of Karan Johar's upcoming movie 'We Are Family', as superstar Shah Rukh Khan reached the sets, where the actors were shooting a promotional interview for the film.

If media reports are to be believed, SRK visited the sets when glamorous Kareena Kapoor and hotbod Arjun Rampal were shooting a promotional interview for their upcoming movie on Wednesday evening.

A surprised Arjun Rampal tweeted about this incident on Twitter for his fans: "surprised Kareena& me by walking into the midst of our interview saying he was part of the family& should be interviewed, ROCKSTAR."

"is by far the most endearing person thank you for today, " posted Rampal, speaking about his 'Om Shanti Om' co-star Shah Rukh Khan.

SRK was shooting near the place where Kareena and others were shooting their interview, media reports stated.

However, SRK is busy these days with his upcoming movie 'RA.One'.

The movie is produced by Khan's production company, Red Chillies Entertainment, and will feature King Khan himself along with Kareena and Arjun.
