Adele is ''too scared'' to have more kids.

The 28-year-old singer was ''frightened'' after having son Angelo, who is now four, with her partner Simon Konecki because she suffered from ''really bad'' postpartum depression, and as a result she is wary about getting pregnant again.

When asked if she's planning to have another child, she replied: ''I'm too scared. I had really bad postpartum depression after I had my son, and it frightened me ... I didn't talk to anyone about it. I was very reluctant.''

But Adele wasn't the only one of her pals who struggled to deal with motherhood.

She added to Vanity Fair magazine: ''One day I said to a friend, 'I f***ing hate this, and she just burst into tears and said, 'I f***ing hate this, too.' ''

The star also admitted she felt ''pressured'' into having kids and ''very inadequate'' after giving birth.

Adele's comments come after she insisted last December she had ''never been happier'' and had recently struggled to write songs because she wasn't feeling ''sad''.

She said: ''I've never been happier. And I've never been healthier. So I'm good. I found it impossible [to write songs] for a while. I didn't know what I wanted to write about ... What's wrong is, I wasn't sad.

'''Hello' is just about reconnecting with everyone else and myself. From the other side, I couldn't get over my guilt of leaving my kid to go and write a record and stuff like that. So [it's] getting over that - getting on the other side of that. It was just, you know, it's in general, just hello to everyone.''

The 'Someone Like You' hitmaker insisted at the time that because of Simon and Angelo she was OK.

She added: ''I know that sounds a bit like I'm trying to write a Hollywood movie but it's only because of him and because of our kid and stuff that I'm all right.''
