Elsa Pataky rang in a milestone birthday on Monday with a whole lot of love from her husband Chris Hemsworth. The Thor hunk took to Instagram to wish his wife of six years a happy 40th birthday with a stunning black-and-white photo of the pair and the sweetest message.

"Happy birthday to the worlds best wife, greatest mum and all round stunning human!! Love you loads and thanks for letting me help blow out the candles," the 32-year-old captioned the shot, which shows him and the Spanish model blowing out candles in honor of the big 4-0.

Pataky, who shares three children with the Australian heartthrob, also got another big surprise later that day in the form of a romantic getaway down under.

"Best birthday ever, thanks for all the birthday wishes! Not sure if @chrishemsworth is attempting to catch me or push me out of the plane here but fun either way!!! @australia #bestimes #love #birthday," the blonde stunner hilariously wrote in Spanish alongside an Instagram post showing her and her hubby boarding a plane while she appears to be suspended in mid-air.

Stay tuned for plenty of romantic Aussie vacation pics!
