Colin Farrell offered up a little TMI about a shave that was a little too close for comfort.

The Lobster star appeared on Monday's Ellen DeGeneresShow, where he revealed the story behind the first sex scene he had to film in Hollywood and the, um, grooming that went along with it.

I was very nervous 'cause I'd never done a sex scene," he explained, joking, "Now, they're just a walk in the park... Not really. They're always uncomfortable."

"I was obviously so nervous," he continued. "Like most men, I had, what you would refer to as 'retro-bush.'"

The director went, 'Oh...,' and I went, 'OK, I'll trim it,'" the 40-year-old actor shared. "I went into my trailer ... and I trimmed ... but I overshot a little bit ... and I looked down and I had a little landing strip, lovely little landing strip."

There was a reason for the candid confession, of course. Farrell told the "narrowing" tale in order to raise money for the CHIME Institute, a charter school in Woodland Hills, California, which provides an inclusive education for children with special needs, who are able to study alongside their non-special needs peers. Farrell revealed that his 13-year-old son, Jack, has attended the school for years.

So at least the hairy situation all led to a good cause!
