DAVID BECKHAM with ROMEO, 8, CRUZ, 6, and BROOKLYN, 12

David and Victoria's boys-soon to be joined by a sister!-are all avid soccer players, naturally. "My greatest achievement is my children," David has said.

SPIKE LEE with JACKSON, 14

They've got game: The son of the director and wife Tonya Lewis inherited his dad's Knicks fandom, standout eyewear and New York attitude.

JACK NICHOLSON with RAYMOND, 19

We'd know that smile anywhere. Jack's youngest kid (with actress Rebecca Broussard) grew up rooting for his pop's beloved Lakers from courtside seats.

SEAN PENN with HOPPER JACK, 17

The actor's son-whom Penn and ex-wife Robin Wright named after pals Dennis Hopper and Jack Nicholson-mingled with movie royalty in Cannes.

JUDE LAW with RAFFERTY, 14

Do they borrow each other's skinny jeans? Proving a flair for fashion runs in the family, the actor and his son (mom is Jude's ex Sadie Frost) made a dashing duo in L.A.

WARREN BEATTY with BENJAMIN, 16

The teen-with his dad at the 2011 NBA All-Star game-clearly got a good helping of genes from mom Annette Bening too. He's the second oldest of their brood of four.
