'Once Upon A Time': Britney Spears, boyfriend Sam Asghari attend 'first premiere' together

It's date night!

Britney Spears and boyfriend Sam Asghari stepped out Monday night to attend the Los Angeles premiere of Quentin Tarantino's "Once Upon A Time In Hollywood," starring A-listers Leonardo DiCaprio, Brad Pitt and Margot Robbie.

Spears took to Instagram to document the moment. "Our first premiere," she captioned a picture of the herself and Asghari looking happier than ever.

The singer wore a red, one shoulder cocktail dress, finishing her look with a loose ponytail, silver choker and black heels. Asghari opted for a tan suit.

Although Spears and Asghari didn't bust out any dance moves on the red carpet, like their "fun summer" Instagram video last week, the duo did show some PDA with a kiss.

Other couples in attendance included Sofia Vergara and Joe Manganiello, Chris Hemsworth and Elsa Pataky, Vanessa Hudgens and Austin Butler, John Stamos and Caitlin McHugh and Robin Thicke and April Love Geary.

There had been no photobombing by Pitt … yet.
