The X Factor boss and his girlfriend Lauren Silverman welcomed their first child together, son Eric, on Friday and on Wednesday the happy couple headed to Manhattan Family Court in New York, where a judge signed an order of filiation, formally acknowledging Cowell as the tot's father in the event of custody or visitation issues.
According to TMZ.com, the new parents also filed papers for Eric's first travel documents and he was subsequently cleared for take-off.
However, the child is unlikely to be boarding a plane anytime soon - medics recommend waiting until babies are at least four weeks old to fly.
But Cowell won't be able to wait around - he is due back in the UK to continue filming for Britain's Got Talent, after jetting across the Atlantic on Friday as his partner went into labour.
