Girls Aloud star Cheryl can't wait for Kimberley to become a first-time mum and said she plans on buying "everything" for the new arrival.
However, when asked if she was getting broody, Cheryl told a group of reporters at Capital's Summertime Ball with Vodafone this weekend (21 June) that it wasn't on her agenda.
"Not at the moment," said Cheryl. "Baby brain syndrome is not something that I want to go through right now."
Strictly Come Dancing star Kimberley, who is expecting her first baby with long-term boyfriend Justin Scott, has previously said that Cheryl isn't ready to start her own family.
In a new chapter added into the paperback version of A Whole Lot Of History, Kimberley spoke of Cheryl's holiday to South Africa earlier this year: "Cheryl told me she'd felt relaxed and free in Cape Town. She'd been partying and having more fun then she'd had in ages. She seemed thrilled to be back to her old self.
"She said she was happy with the way things were now and that she didn't feel ready to settle down and start a family just yet. It became abundantly clear that the two of us were in totally different places."
