The 'Girls' star has shared a photo of the beautiful moonstone and peridot ring and gushed about her other half, dubbing him "boyfriend of the year".

She wrote: "Early anniversary gift from boyfriend of the year @jackantonoff (care of @eriebasin in Brooklyn.) Turn of the century moonstone and peridot. I will so enjoy looking at it while I type words #ringbrag #jewelrybitch #friendshipring (sic)"

Meanwhile, despite Jack giving Lena a ring, the happy couple have no plans to walk down the aisle just yet, with the 29-year-old actress previously admitting she's "intimidated" by marriage.

She said: "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. So I don't want to go in and kind of pale in comparison."

The couple had previously insisted they wouldn't get married themselves until same-sex marriage was legalised in the United States and when the ruling was approved in June 2015, they received lots of text messages from their close pals asking when they would be tying the knot.

She added: "We were thrilled, we were celebrating. And then suddenly the texts just started coming from our friends, from our mothers, from our exercise instructors. Being like finally it's your time. And we kind of looked at each other we were like, 'Oh God what have we done?'"
