Daniel Radcliffe supported his girlfriend Erin Darke during her opening night of The Spoils in New York City.

Darke stars in The Spoils which debuted on Tuesday night at Qi Bangkok Eatery in New York City. The New York Times added that Darke stars alongside Jesse Eisenberg.

The Spoils, which was written by Eisenberg, tells the story of a disturbed and disliked grad school drop out (Esienberg) who has a plan to ruin the relationship of his childhood crush (Darke) and her current fiancé.

Darke has previously been featured in HBO's Girls and was seen in Still Alice.

Radcliffe opened up about his relationship with Darke during a previous interview with People. The two have been dating since they met on the set of Kill Your Darlings back in 2012. Radcliffe confirmed their relationship officially in 2014.

"I'm going out with my best friend at the moment. And that's, I think, the way it should be. If you can get to a point where you're dating or married to somebody you consider your best friend, that's what will make it work," said the Harry Potter star.
