The Motorcycle Diaries star welcomed baby boy Lazaro with Argentinian actress Dolores Fonzi last year (09).
Online reports surfaced this week (begs01Feb10) suggesting Bernal had ended their longterm relationship after learning he may not be little Lazaro's biological dad, but Bernal's spokesperson has denied the reports to People.com and a source close to the star insists the rumours are false.
The insider says, "It's completely untrue. (They) are happy together and they love their son. This is totally made up."
