Brody Jenner and girlfriend Avril Lavigne stumbled into Mark Mahoney’s Shamrock Social Club tattoo parlor in Hollywood this week after saying they haven’t slept in two days and said they wanted matching tattoos (I wonder what would make you stay awake for two days?)!

RadarOnline.com has learned exclusively that pop star Avril Lavigne and reality show star Brody Jenner sealed their new love by both getting the word F**K inked on their ribs this week.

Appearing very ragged the couple said they had “not slept for two days” as they staggered around Mark Mahoney’s Shamrock Social Club tattoo parlor in Hollywood.

A source told RadarOnline.com that Avril and Brody looked awful when they arrived at the shop. “They were laughing and said they had not slept in two days. They were completely, utterly out of it.

“Then nobody could believe it when they said they wanted the word F**K written on their ribs.

Believe it or not this is actually not the first time the two lovers got matching tattoos. Back in April the two got matching lightning bolt tattoos (sweet right?). Avril got her lightning bolt on her forearm Brody had his behind an ear.
