Sinead O’Connor displayed the initials “B” and “Q” on her cheeks while onstage at Bestival music festival.

It appears the initials stand for Brendan Quinlan, a mystery man Sinead O’Connor, 46, alludes to on her website when vaguely discussing her new tattoos.

Written in red calligraphy, Sinead O’Connor showed them off as she performed at the 10th anniversary of Rob Da Bank’s music festival, in the Big Top on Friday night.

On her website, Sinead O’Connor wrote: “It’s what it is … un ange passé 😉 There’s a bottle of Agent Provocateur in someone’s room that belongs to me.”

Using the French phrase for “an awkward silence” does nothing to make the tattoo’s meaning more clear, but the Irish Sun claims the inkings were done after a falling out with a man, reportedly bearing those initials.

Earlier this year, at Glastonbury, Sinead O’Connor debuted another new addition to her tattoo collection – a tribute to her Rastafri beliefs on her right hand.

The design features the lyrics “The Lion of Judah shall break every chain”, from Bob Marley’s track Lion Of Judah.

In swirling script, the tattoo takes up the majority of the back of Sinead O’Connor’s hand.
