Team USA's Ashlyn Harris -- Obama Has a Crush On Carli Lloyd!

The entire country is OBSESSED with Carli Lloyd ... including the President ... so says Team USA's Ashlyn Harris who tells us the squad thinks POTUS has a little crush on #10.

Ashlyn -- one of the goalkeepers on the US team -- was at LAX when she told us one of the coolest post-World Cup moments was when the gang got a call from President Obama.

Harris says POTUS congratulated the team and officially invited them to the White House -- but says afterward, the ladies thought Obama seemed a little smitten with the Queen of the Hat Trick.

Hey, can't blame the guy ... GO USA!
