'Girls' season 6 news: Lena Dunham pens emotional goodbye to HBO series; Hannah and Adam have a child?

Lena Dunham, who stars in and created the HBO comedy/drama "Girls," recently wrote an emotionally charged Instagram post about the show's impending conclusion. The Golden Globe-winning series will air its sixth and final season in 2017.

"Girls," which debuted in 2012, follows the lives of four young women living in New York City. Dunham plays Hannah Horvath, an aspiring writer. Her closest friends include the unpredictable Jessa Johansson (Jemima Kirke), the ambitious Marnie Michaels (Allison Williams), and the bubbly Shoshanna Shapiro (Zosia Mamet). 

Dunham, who also serves as the show's executive producer and its occasional director writer, recently took to Instagram to say goodbye. In a series of posts, she expressed her sorrow over the show's end and gratitude for all the support it has received. The actress also talked about how "Girls" changed her life.

"I know I'm not alone in the 'Girls' family when I say this is the end of the largest and most potent chapter of my life so far," she wrote. "Before 'Girls' I had zero identity, zero self-love and an urgent sense of untapped creative desire...

"When we shot our pilot six years ago, I never dreamed that I could be so fulfilled by the process of art-making, of collaboration, of honest expression," she added. "And so through this show I developed an identity, gained a new kind of family and began my life in earnest," Dunham continued.

Meanwhile, photos taken from the set of "Girls" season 6 revealed Dunham wearing breast pumps strapped to her chest as co-star Williams held a baby nearby. Other on-set photos taken in previous months show Dunham's Hannah with a growing baby bump. Fans are thus speculating that the sixth season could reveal Hannah pregnant, possibly with Adam's (Adam Driver) child.

"Girls" season 6 will debut on HBO in 2017.
