Robert Downey Jr has undergone quite a drastic transformation after shaving off all his hair and he certainly made us look twice. 

The Iron Man actor is famous for sporting thick, luscious, short dark hair and trademark look has barely changed over the years, except for switching up the colour slightly over the years. 

However, that’s all gone out the window after the 57-year-old actor gave his children access to the clippers and he’s now looking like a whole new man. 

Attending the Governors Ball on Saturday with his wife Susan, 45, Robert posed for photos sporting a clean bald dome and, honestly, who knew he had such a perfectly shaped head? 

Robert, looking dashing in a black suit, white shirt and tie, seemed pretty excited to show off his transformation as he smiled widely for photos alongside wife Susan, who stunned in a layered black maxi dress. 

His makeover is the handiwork of Robert and Susan’s two children, Exton, 10, and Avri, eight, who were given permission to whip off his spiky brown hair last month.

In an Instagram video, Robert is seen explaining to his offspring: ‘I don’t want to have to wear a bald cap, so will you guys shave my head?’ 

Avri asks if that’s ‘even appropriate’ but he quickly has a change of mind and is seen laughing mischievously while handling the shaver. 

‘Great job guys,’ Robert tells his boys after they take the clippers to his hair. 

His eldest Exton then tells his dad: ‘Keep your money, Avri’s got a better idea,’ before Robert unveils the back of his newly bald head with a bright orange pumpkin painted on it. 

It’s all for a good reason though as Robert is preparing for a role in upcoming HBO limited series The Sympathizer, which will follow a half-French, half-Vietnamese man who served as a spy for Communist forces during the Vietnam War.
