X17 EXCLUSIVE - David And Victoria Beckham Take Baby Harper To Get Passport

David Beckham held on tight to daughter Harper as he and wife Victoria left the Wilshire Federal Building in Los Angeles.

Becks and Posh were there to get a passport for their baby daughter. Since the little bundle is an American citizen by birth, she's required to have an American passport. And BOTH parents must be present to obtain the legal document for a minor.

An X17 photographer tells us:

"Security was extremely tight while David and Victoria walked in. Armed Federal agents stood guard outside the building while they handled the paperwork inside."

Sounds like a trip abroad is right around the corner!

The jet-setting family frequently makes the trip home to England. Time to add one more Louis Vuitton suitcase to the bunch!
