Ed Sheeran shows off his new tattoo to the crowd during his performance at Q102′s iHeart Radio venue in Bala Cynwyd, Penn., on Monday evening (September 24).

Earlier in the day, the 21-year-old British singer stopped by Good Day Philadelphia to chat about his tour — which he just added more dates to. Details inside!

“One of them is kind of a getting-back together song. One of them is an appreciation song,” Ed shared with MTV of the tracks he wrote on One Direction‘s new album. “I can’t say the titles. The song that I think will be the single, one of the singles, is kind of a very sweet song.”

He added, “It was written about the best things about someone, kind of like the things you wouldn’t expect. You’ll have to hear it. I can’t really say too much ’cause it’s their album. I want them to be the first ones to announce it and stuff.”

FYI: Ed is playing his Martin guitar.
