The happy couple documented their Valentine's Day together on Instragram
In a sweet Valentine’s Day Instagram post, Schwarzenegger shared a pic of himself with the singer, captioning the photo “luckiest guy in the world.”
Cyrus shared her own happy snap of the couple, as well as some shots of a pretty impressive balloon arrangement, courtesy of her 21-year-old beau.
The pair have been practically inseparable since they first began dating in November. Just last weekend, the two were spotted packing on the PDA during Grammys weekend.
“They were kissing and cuddling at a VIP table,” an onlooker said of their PDA last weekend. “They whispered in each other’s ears and were smiling and laughing.”
But for now at least, the 22-year-old singer plans to take the relationship slowly after a painful split from fiancé Liam Hemsworth in 2013.
“Miley learned her lesson the hard way the first time and is being extra cautious about this relationship,” a source told PEOPLE earlier this month. “She doesn’t want to get her heart broken again.”
