Scarlett Johansson has ''body worries''.

Despite her sex symbol status, the actress star has issues with her figure like all women do, but her all-action role in 'Avengers Assemble' as Black Widow got her into the best shape she's ever been in.

Robert Downey Jr. has ''missed'' his son ''a lot'' while promoting 'Avengers Assemble'.

The 47-year-old actor - who already has son Indio, 18, with ex-wife Deborah Falconer - and his spouse Susan Levin welcomed baby Exton Elias into the world two months ago, and he loves being around his ''really cute'' little one, but wishes he could have spent more time with him since his birth.

Robert Downey Jr. feels like a ''big brother'' to Scarlett Johansson.

The 46-year-old actor - who will star alongside the blonde beauty in 'Avengers Assemble' - has grown attached to his cast mates while shooting the superhero film, and he sees Scarlett, who plays the Black Widow, as a sister figure having previously worked with her on 'Iron Man 2'.
