And no, your eyes aren't deceiving you, that's not actually Bradley Cooper hanging out with Mel, that's the longtime actor's fifth child with his ex-wife Robyn Moore Gibson.
It turns out that Milo is already following in his famous father's footsteps as he has a role in the upcoming war flick alongside Andrew Garfield.
The look-alike father and son duo appeared to be in the best of spirits during the swanky affair celebrating the release of the future film, which is slated to hit theaters on Nov. 4.
The up and coming actor is also the older half-brother to Mel's six-year-old daughter Lucia Gibson and is set to welcome another addition to the family in the very near future as Mel is currently expecting his ninth child with his girlfriend Rosalind Ross.
Looks like there could be more Gibsons in Hollywood coming very, very soon!
