Despite reports that Sam Worthington and Lara Bingle had welcomed a son earlier this week, doubts have been cast after screenshots from Worthington’s sister emerged.

The notoriously couple had never even confirmed that Bingle was pregnant, let alone confirmed the birth, but sources said their first child was born on Tuesday.

Now Worthington’s sister, Lucy Edwards, has seemingly denied that any child was born.

Friends posted well wishes on Edwards’ Facebook wall, congratulating her on the birth of her new nephew, and she responded to one such message, writing, “Sorry [name]…no arrival”.

Less than 24 hours later, though, Edwards wrote on mother Julia’s wall that she was “feeling happy”.

Bingle’s publicist has denied comment on the reports.
