Now we know why Paulina Gretzky broke our hearts and didn't post any hot Halloween costumes to her Instagram page last week!

The 24-year-old hockey heiress was in Shanghai, China supporting her fiancé, golfer Dustin Johnson, who won the HSBC Champions tournament (and a cool $1.4 million to boot).

The blond starlet posted a sweet Instagram photo of the happy couple on Sunday celebrating Johnson's win with a celebratory kiss.

"Congrats baby @djohnsonpga!! So happy I could be there for another WIN," Paulina captioned the pic, which featured the photogenic socialite sporting a fitted cardigan over a black blouse and black skinny jeans.

Seems like Wayne Gretzky's daughter is a lucky charm for the eight-time PGA Tour winner; the sexy WAG has followed her husband-to-be to many of his tournaments including the RBC Canadian Open in Toronto and the Augusta National Golf Course.

The twosome have been joined at the hip ever since Johnson proposed to the Flare cover girl in August and have traveled around the world (in private jets, natch) to exotic locations where they have mingled with koalas and tigers.

We're calling it: Paulina and Dustin are the next Kim and Kanye!
