Another reason to love Lena Dunham! The Girls creator/director/actress tells Interview magazine that she is not one of those stars who won't speak publicly about her relationships.

"You fell in love not that long ago," actress-writer Miranda July, who was interviewing Dunham, 26, for the magazine said. "We've spoken about him already but would you like to state the full name of this person?"

"Oh, I'm totally fine to state his name: It's Jack Antonoff," Dunham said of the guitarist for the band Fun., 28, who she began publicly dating in September 2012. "I know there's some rule that you're not supposed to talk about your boyfriend publicly just because it seems like all starlets under the age of 33 have decided not to do that, but if you're in love with someone great, then I don't understand why you wouldn't tell everybody," she added. "You don't have to post naked pictures of them on the internet or tweet pictures of your Christmas celebration, but I feel like, in a way, he's my best advertisement, so I'm like, 'Why would I not tell people who ask?'"

And Dunham also has no problem saying "I love you" to those who matter most to her. "I've always been a big 'I love you'-sayer and stuff. But then I worry," she admitted. "Jack once overheard me calling someone else 'baby bug,' or some stupid name that I've called him before. I was like, 'What if he now thinks I'm just a big disingenuous piece of crap?' That kind of thing gives me anxiety because I want everyone I love to know how much I love them."

So how do the HBO star and indie rocker make time for each other in their hectic schedules?

"Well, Jack is the first person that it hasn't been an issue with," Dunham said of finding a man who was accepting of her career goals. "I was concerned that I was going to end up with like a pie-maker or a guy who lived in a van, and then my big appeal was going to be that I was going to be able to take that guy out of his van. But Jack works so much -- I always say that he makes my job look like I work part-time in the gift shop at an old-age home," she joked. "He's just constantly doing it, and it gets me invigorated about what I'm doing and reminds me of what's important."
