Justin Bieber concert: Malaika, Arbaaz arrive together with son Arhaan

With the international singing sensation Justin Bieber taking centre-stage at the DY Patil Stadium in Mumbai, it's the turnout of the who's who of Bollywood that has been making waves on the social media.

Quite relishing the event, Alia Bhatt has been constantly posting pictures with her sister Shaheen on her Instagram account. But what caught everybody's attention was a certain duo, accompanied by their son, making a joint entrance in the show.

Malaika Arora and Arbaaz Khan, who separated last year, arrived together at the show. Coming together for their son Arhaan, the former husband and wife looked comfortable with each other.

While Malaika looked classy as always, the boys - Arhaan and Arbaaz - chose to keep it casual.

Earlier in the day, pop sensation Bieber kickstarted his concert in Mumbai.

Veteran actress Sridevi was spotted at the event with husband Boney Kapoor and their younger daughter Khushi Kapoor.

Raveena Tandon, who was also spotted at the event told ANI, "I think it is great, we should have more show like that. We can see everyone go crazy about him [ Justin Bieber].
