Aamir, along with Karan Johar, was present at Twinkle's debut book launch here on Tuesday.
Her book "Mrs. Funnybones" was launched with a live version of Karan's celebrated talk show "Koffee with Karan" with Twinkle as the main guest. Karan asked Aamir did he think Twinkle was a good actress? To that, Aamir jokingly replied: "I thought she was fantastic."
`All of us have different abilities and Twinkle is really talented in some of the most amazing activities like insulting people, she is an expert in insulting people. All through my life, since I've known her she has just constantly insulted me,` he added.
The book launch also saw Twinkle's husband Akshay Kumar, mother Dimple Kapadia, veteran actress Jaya Bachchan, Sussanne Roshan and Sonali Bendre in attendance.
