Britney Spears gives Jamie Lynn Spears some parenting tips

‘It was wonderful to be able to spend time with her and just be girls again,’ Jamie admits.

‘We painted our nails and did stupid stuff, and we had our private time too.

'To be able to be in the privacy of our own home and just be sisters again was wonderful.’

‘She said: “There’s going to be some long nights, but it’s completely worth it,”’ Jamie tells OK!

The Zoey 101 star is due to give birth to fiancé Casey Aldridge's baby this summer.

'Britney loves Casey,' she says, 'She's met him a bunch of times. They were riding 4-wheelers and stuff together. They got along really well.'
