Katherine Jenkins has said that she is finding it "difficult" to perform love songs following her split from Gethin Jones.
The couple broke off their engagement in December, allegedly over her "demanding" career goals.
Speaking to The Mirror, the singer said: "I sing from my heart, so it's been difficult to sing love songs. Those songs were written before everything happened.
"I got really emotional at the end because I know the journey I've been on."
She added: "When I first started this tour I was a bit of a mess. I didn't know how I was going to get through it. I looked at my list of songs and they're all about love and heartbreak... But that's my problem."
