Britney Spears recalls on-stage kiss with Madonna in candid Instagram video

Nearly two decades after it happened, Britney Spears has spoken about her on-stage kiss with Madonna at the 2003 VMAs.

The pop singer posted a video to her Instagram where she answered a couple of fan questions. The last question she addresses in the short video is "have you ever kissed a girl?"

Spears answered: "Yes, and her name is Madonna" while smiling.

The 'Toxic' singer and Madonna kissed on stage with Christina Aguilera as the opening act of the show.

Another question answered in the fan Q&A video was Spears' favourite car. "My dream car is probably a Bentley. I've never owned one or driven in one, but it's definitely my dream car," she said.

She continued the video: "Number two is have I ever fallen onstage. Yes. I was on tour — the Dream within a Dream tour — and I had rain boots on and there was a rain sequence and I slid across the whole stage and I embarrassed myself in front of of thousands of people, and it was pretty embarrassing," referring to an incident way back during her 2002 North American tour.

She also revealed to fans that her favourite Halloween costume was when she dressed as a fairy one year.

This isn't the first video where the pop star has answered "fan questions", though many people in the comments have wondered where these questions even came from.

One person commented, "I've never seen anyone ask these questions in the comments," as another asked, "Who told you that these were our questions?"
