Safai simply captioned the post with a black heart, and didn't appear to tag her new beau. But, as it turns out, it's the same mystery man that she walked the AMAs' red carpet with last week - Neils Houweling.
So, who exactly is Neils Houweling, and what do we know about him and Shiva so far?
He's been connected with Shiva for a while
Shiva's Instagram post comes more than five months after Houweling made the couple's blossoming romance first known on social media, via a sweet pic of his own.
Back in June, he posted a picture of himself sitting on an outdoor couch with a woman's hand embracing his neck. And although a face isn't seen, the hand is tagged as - you guessed it - Shiva Safai.
Houweling also has an Instagram Story Highlight reel dedicated to Safai, which includes a cosy picture of the pair with an overlying GIF that reads, "I love you!"
He's originally from The Netherlands
Neils is of Dutch heritage, and recently revealed in an Instagram Q&A with his fans that we was born in Amsterdam, capital of the Netherlands. However, he was raised between Costa Rica, Uruguay, Florida, New York and Los Angeles, making him pretty multilingual.
He's a DJ and music producer
Performing under the stage name, "MOST", Houweling is a DJ and music producer. Neils first turned to music when he was in New York and Miami, where he originally recieved his training. Most recently, Neils spent around eight months in the Netherlands working on new music, which is yet to be released.
