The 'Stronger' hitmaker has recently revealed she is expecting her first child with her husband Brand Blackstock just a month after tying the knot, but Adele told her last year not to force time and become a mother too early.
She said: ''I ran into her at the Grammys last year... she said 'Girl don't have a baby because everything else will go on the back burner.''
Meanwhile, the 31-year-old singer, who won the first ever series of talent show 'American Idol' in 2002, took to Twitter earlier this week to share her excitement at becoming a mother for the first time.
She wrote: ''I'm pregnant!!! Brandon and I are so excited! Best early Christmas present ever (sic).''
However, the news didn't come too much as a surprise to the public as the 'Since U Been Gone' star has been open about her to desire to have a baby for some time now.
She said previously: ''More than anything, next I want a baby ... My record label is freaking out because all I can talk about now are babies.
''We're really excited and want to get our family started!''
Kelly's husband has two children, 11-year-old Savannah and seven-year-old Seth, from a previous relationship.
