The vocalist was performing in a harness four years ago and has to get used to being without one on stage.
Pink thinks she sings better upside down.
The vocalist has recently been performing without a bungee rope for the first time in four years a device that was used on 2009's 'Funhouse' tour, which featured a host of acrobatics.
The 33-year-old played London's iTunes Festival this week.
She told The Daily Star newspaper: ''This is my first gig in a long while and I didn't know how it would go.
''I do think I sound better upside down. I'm finding it hard remembering the words singing standing up.''
In between the active gigs a few years ago and her new album 'The Truth About Love', Pink gave birth to daughter Willow.
The star - whose real name is Alecia Moore - said: ''I miss the bungee. I loved all the acrobatics so we are trying to figure out what to do for the next tour, something rad.
''It's amazing to be back. I've been pining for a stage. But having a baby changes the logistics of touring. I don't hang out with my bandmates at the bar anymore.''
However she insists motherhood will not alter her personality.
She revealed: ''I haven't lost my edge. Having a baby doesn't change your attitude.
''The new album is about love but aren't they all? I wrote it seven months after she was born.''
