Lena Dunham was 40 minutes late to her first date with Jack Antonoff.

The 'Girls' actress -- who has been dating the fun. guitarist since 2012 -- feared she had blown her chance of a possible romance before she had even met the 30-year-old star when she failed to turn up on time for their blind date.

When asked if she had any tips for asking a guy out, she said: "I was set up with my boyfriend on a blind date; I was like 40 minutes late and now we live together.

"So I really don't know how you're supposed to go about this.

"I guess I would say I'm a big proponent of (being) honest and not playing games, so if you want to spend time with someone in a romantic setting, and you've picked up on the signal that they might too, you should just ask them to go do something."

Dunham, 28, also admitted she regrets not going on more dates during her mid-twenties instead of spending a lot of her time vomiting at her friends' houses.

She added to Time Out magazine: "I have never asked anyone out successfully -- that should be said right here.

"I think something I feel embarrassed about in my twenties is that I didn't do enough real dates.

"I feel like all I ever did was just go over to people's houses and throw up. I just didn't live that dream, so you go forth and do that."
