It’s the most popular social networking tool in the world.

But rapper T-Pain took his love of Facebook a little too far recently when he got a Facebook tattoo on his arm.

‘You don’t have to like me’, reads the tattoo, with the site’s trademark thumbs-up sign.

T-Pain posted a picture of the new ink on Twitter, with the caption:

‘I get a tatt every time I come to Hawaii. I think this ones pretty sweet, unless facebook shuts down soon.’

Not the first: Rapper Gucci Mane has also had a questionable tattoo

The 25-year-old, real name Faheem Rasheed Najm, says his stage name is short for Tallahassee Pain, after his birthplace in Florida.

As well as enjoying success as a solo artist, T-Pain has made several guest vocals spots for artists such as Kanye West and Chris Brown.

He is also credited with making the use of auto-tune in tracks popular, influencing songs such as Snoop Dogg’s single Sexual Eruption, Lil Wayne’s single Lollipop, and Kanye West’s album 808s & Heartbreak.

T-Pain has been married to wife Amber since 2003, and hit song ‘I’m Sprung’ is dedicated to her.

The couple have three children, daughter Lyriq, son Muziq, and son Kaydnz Kodah.

Ummmm…T-Pain are you that hard up for attention that you had to get a Facebook tattoo? WTF were you thinking?! SMH.
