Mila Kunis and boyfriend Ashton Kutcher decided to spend their Sunday kicking back at the foot spa in L.A., and this isn't the first time the couple have gotten their tootsies worked on together!

The brunette beauty kept it classic in jeans and a white button down, while her Two and a Half Men beau channeled his inner hippie in Birkenstocks!

Later on in the evening, the pair went for a curry dinner at The Great India restaurant in Studio City before heading home and making it an early night.

They seem to be inseparable lately, and we wouldn't be surprised if Ashton puts a ring on it soon!
