Gaga boo-boo!

And down goes Gaga!

Finger-flipping Lady Gaga took a nasty spill at Heathrow Airport in London yesterday, falling to the floor in thigh-high leather boots with outrageous platform heels.

Two members of Gaga’s entourage were quick to help the “Poker Face” singer back to her feet, and she shuffled out of the airport with no further drama.

Gaga’s rep could not be reached for comment.

The star — who crossed The Pond to perform at Elton John’s White Tie and Tiara Ball — has been all over the news of late.

Jerry Seinfeld took her down a peg Monday during a hilarious rant on WFAN — two weeks after Mets officials gave Gaga access to Seinfeld’s luxury box at Citi Field, where she flipped off the crowd.

Then Gaga took her boorish act last week to Yankee Stadium, where she crashed the clubhouse, infuriating team brass.

Amazingly, Gaga stayed out of trouble in a most unlikely place — a strip joint. She visited HeadQuarters on West 38th Street Monday, delighting guests in a drama-free evening.

Meanwhile, a Web site in Russia reported that a businessman there paid $1 million to appear in Gaga’s latest video, “Alejandro.”
