Score one for the gay agenda.

“Girls” star Lena Dunham appeared on “The Ellen DeGeneres Show” on Friday and revealed why she and her boyfriend of four years, musician Jack Antonoff, have not yet married.

According to Dunham, it’s the legalization of gay marriage that has prevented her and Antonoff from entering whatever might pass as wedded bliss for these two.

The actress previously vowed not to get hitched until everyone was allowed to wed. With marriage equality now the law of the land, Ellen asked the reasonable question: So what’s the deal with your wedding?

Cue Excuse No. 2, which surprisingly also revolves around gay marriage.

“We were hiding behind fake liberal ideals,” Dunham cracked, before explaining, “I’m excited to marry him at some point, but it felt like a lot of pressure to just go for it that day [when gay marriage was legalized].”

“I feel intimidated, because I don’t want to espouse any stereotypes, but gay people are kind of killing it at weddings right now. They’re kind of winning at weddings,” Dunham said. “So I don’t want to go in and just pale in comparison to all these [gay weddings].”

At least Dunham has fully committed to coming up with reasons for why she can’t tie the knot.
