Robert Downey Jr. is nervous about welcoming his first daughter into the world.
The 'Iron Man 3' star, who already has a two-year-old son, Exton, with his wife, Susan Downey, recently confirmed she is expecting a baby girl and admits he's been asking all of his friends for advice, as he doesn't know what to expect.
The 49-year-old actor, who also has a 20-year-old son, Indio, with ex-wife Deborah Falconer, told E! News at Comic-Con in San Diego, California over the weekend: ''I've never had a daughter before, so I don't know what really prepares a dad. I'm asking around. But I did my part and now I'm just going to show up and do what I'm told.''
The 'Avengers' star's eldest son recently checked into a rehab facility after being arrested for cocaine possession and allegedly suffering a relapse.
A source previously said that Robert - who previously batted drug addiction - is ''very proud'' that Indio decided to seek help.
The insider said: ''Robert clearly understands the struggle, and while of course this relapse was very upsetting to him, he is very proud of his son. Indio truly wants to stay clean. And no matter what, his dad will be right there with him.''
Robert released a statement the day after Indio's arrest on June 29, claiming his son ''likely inherited'' his weakness for drugs, but is hopeful he can overcome his issues.
