'Wedding wouldn't be complete without one shot from Dads out dated blackberry camera. Love seeing all so happy’ the 57-year old country singer captioned the snap.
The other low resolution snap show Miley and Liam locked in an adorable embrace.
'Congratulations @LiamHemsworth @MileyCyrus Long live love!!!!!' read the caption.
In March, a source told Entertainment Tonight that Miley was planning a very secret, spur-of-the-moment wedding and that friends and family would only find out the plans at the last minute.
"She hasn't announced anything because she is being very secretive so only their friends will know and at the very last minute," they said. "This time they are doing everything their own way."
