Josh Duhamel injured himself with Julianne Hough's curling iron.
The 40-year-old actor has been left with painful blisters on his fingers after tripping over his 'Safe Haven' co-star's hot hair tool and catching it at the heated end.
He explained: ''I tripped over Julianne's curling iron cord and grabbed the wrong end of it on our press tour. So I had to put Band Aids all over my fingers. We put them under ice but they're a little blistered.''
Josh - who is married to Black Eyed Peas star Fergie - also admitted he is obsessed with Taylor Swift's 'I Knew You Were Trouble' and annoys his loved ones by singing it all the time.
He told People magazine: ''I don't know if I should admit this but I've had Taylor Swift's 'I Knew You Were Trouble' in my head for three days. To the point where everybody was telling me to shut up. It's a really good song.''
