Superstar Aamir Khan is overwhelmed with actor Ranbir Kapoor's performance in "Ae Dil Hai Mushkil", and calls him a great artist.

Aamir took to Twitter to laud filmmaker Karan Johar's directorial venture.

"Ae Dil Hai Mushkil", also starring Aishwarya Rai Bachchan, Anushka Sharma and Fawad Khan, clashed with actor-filmmaker Ajay Devgn's "Shivaay" at the box office.

"Just saw 'Ae Dil...'. What a film! I just loved it! Karan has hit the ball out of the stadium. Ranbir, Aishwarya and Anushka have just killed it. Ranbir is the best actor! Period! A must see!" Aamir posted.

Produced by Fox Star Studios and Dharma Productions, the film released on Friday.
