In a new interview with the UK's Red magazine, Spice Girl Emma Bunton admits that returning to work so soon after the birth of her son Beau Lee, 10 ½-months, was difficult.  While she had a "great time" on the newly-reunited Spice Girls' world tour, the 32-year-old singer says she "should have thought about it more" before committing to such an ambitious schedule.

It's tough for any woman returning to work straight after having a baby.  I didn't want to be in the gym 24 hours a day, instead of being with Beau. And I wanted to breastfeed for the first couple of months.

Emma -- who says she enjoys "being curvy" -- did lots of walking to get herself stage-ready, but couldn't do sit-ups as a result of Beau's delivery by C-section, something she said was necessitated because she was "overdue." When she did finally perform with the Spice Girls, Emma admits she at first felt "self-conscious" about her postpartum figure -- but eventually she learned to relax.

One night, I was up on stage and it just hit me: Hold on, Emma, everyone knows you've just had a baby, enjoy it.

Beau is the first child for Emma and longtime boyfriend Jade Jones.
