Lisa Osbourne - who is heavily pregnant with the couple's second child - spent a night under observation after her vehicle was hit from behind on Monday (27.04.15) and though she said she was "losing her mind" being away from home, she was relieved to know her unborn baby was fine.

Posting a picture of herself in hospital, she wrote alongside the image: "When some a-hole rear ends your car & you have to spend 24 hours in L&D getting monitored as standard protocol. Baby is fine, but I am losing my mind up in here!"

And Lisa found it tough being unable to put her three-year-old daughter Pearl to bed.

She added: "Cried on the phone with Pearl bc I wasn't there tonight to put her to sleep. Feeling so much sympathy for the women who have to be in this unit on bed rest for weeks and months due to serious complications.

"My heart goes out to you."

Though she wasn't hurt, Lisa's hospitalisation left her family worried.

Her mother-in-law, Sharon Osbourne, tweeted: "Sad today my daughter-in-law went into hospital yesterday...I need to hear she is coming home. (sic)"

Happily, Sharon's wish was granted shortly afterwards and Lisa was released from hospital a few hours ago.

Alongside a picture of herself and Pearl, she wrote: "Finally back at home with my crew! Thanks for all the well wishes. Baby & I are good :) (sic)"
