(Cover) - EN Star Style - Pink says trying to do yoga with a six-week old baby in tow is more difficult than she initially thought.

The American songstress and her husband Carey Hart welcomed Willow Sage into the world on June 2.

The 31-year-old star is currently dabbling in a spot of yoga to keep herself healthy following the birth of her first baby, however the singer says completing the exercise uninterrupted is more difficult than she originally envisaged.

Pink took to her personal Twitter page to vent her frustrations.

"just tried 2do yoga class w/ a 6 wk old.even dressed her in buddha onesie thinking it'd keep her calm. wrong. so wrong. no dwnwrd dog 4 me:) (sic)," she wrote.

Pink has previously revealed that motherhood has changed her life, citing that it used to involve "whiskey, tears, and cigarettes now it's snot, tears, and the colour of poop". (C) Cover Media
