Britney Spears has finally confirmed her steamy past romance with actor Colin Farrell .

While the rumors started flying after their entangled red carpet appearance in 2003, Spears formally detailed their fling for the first time in her memoir The Woman in Me and said she was still reeling from her 2002 split with Justin Timberlake when they met.

The Toxic singer reportedly described her time with Farrell as a sultry two-week brawl.

Brawl is the only word for it we were all over each other, grappling so passionately it was like we were in a street fight, wrote Spears in her upcoming memoir, according to an early copy obtained Thursday by Time magazine .

Spears explained she was introduced to Farrell through a club promoter friend while the actor was filming S.W.A.T. in 2002. She privately visited Farrell on set when he was working. And they publicly arrived arm-in-arm at the January 2003 premiere of his film The Recruit .

It had been nine months since Spears and Timberlake split after three years together.

As I had before when Id felt too attached to a man, I tried to convince myself in every way that it was not a big deal, that we were just having fun, that in this case I was vulnerable because I wasnt over Justin yet, wrote Spears in her book, as reported by Time.

Their united arrival certainly was a big deal to fans, the entertainment press and the pop culture world, as countless photos of the suspected couple laughing and gazing at each other with Farrells arm draped over Spears shoulder hit the news.
