Posting a picture of the front cover of US Star magazine – which bore the headline ‘Brad Moves In – Kate can’t keep her hands off him’ – Oliver began his cheeky rant about the A-list actor moving in with his sister.
‘Yeah and it's been hell!! He's messy as shit! He drinks out of the f****** carton and leaves the door open when he's taking a dump!! And this is when he's at MY house!!!
‘He's already calling me brother and has driven a wedge between myself and my real brother Wyatt who now won't speak to me.. he insists my kids call him uncle B and lost my youngest at the Santa Monica pier for 2 days.. thank god for amber alert..’
Oliver then went on to joke that even his mum, Goldie Hawn can’t help flirting with the Hollywood hunk.
‘My mom's overtly flirting with him! Shes wearing these little nighties around the house now?! But ALL DAY!! Like at 3pm! And Pa just keeps saying "All right!! It's Brad Pitt!!"
Concluding his hilarious post, Oliver said: ‘Anyway not going well.. so BP.. it's time to move out man.. I need my life back dog.. I'll smoke one more bowl and then get the f*** out.. we thank you.. oh and I found your medical bracelet so I'll get that back to you.. ok..’
