Pregnancy made Aguilera emotional on tour

Singer Christina Aguilera had to struggle with songs during her recent tour because pregnancy made her emotional.

Aguilera would cry while singing and though fans liked seeing her get into her songs, only her dancers knew the real reason behind her breakdown, reports contactmusic.com.

She said: 'I remember one night I came out and sang 'Beautiful' and I was really crying while singing the song. I couldn't help myself. The audience just went crazy but my band was like, 'Oh, man, this poor girl.' That was the first time I'd ever bawled onstage, but it came at the right song. At least I wasn't crying during 'Dirrty'.'

The singer is expecting her first child in early 2008.
