She's running out of time to pick a baby name!

Married at First Sight star Jamie Otis and her husband Doug Hehner are currently expecting their second child together — a baby girl! — and even though she just entered her third trimester, she revealed that she and Doug still haven't decided on a name for their daughter.

The 30-year-old took to Instagram on Saturday, June 10 to share an adorable pic with her younger sister — who is also pregnant — taken at her baby shower. Both ladies stood with their bellies touching to compare the size of their baby bumps.

"My little sissy is due [six] weeks before me … today we showered her sweet baby girl with gifts!! She's naming her Natalynn," Jamie wrote in the caption. "Doug and I are still unsure what we are going to name our little one…I guess we better figure that out soon. It's so fun being pregnant together!!"

It looks like the couple is still undecided on a name, even though they did reveal that they were leaning towards the name Henley. Back in January, Jamie shared a photo on Instagram of her and Doug standing underneath a street sign with the name "Henley" written across it, and she said she was taking it as a sign that she was supposed to name her baby girl Henley — and it turns out that that name has a very special meaning to Doug and Jamie.

“When Doug and I first got married — we were married at first sight, so we didn’t obviously know each other very well — and the first morning, we wake up and he goes, ‘You’re Jamie Nicole Otis, and I’m…‘Douglas Edward Henley?'" Jamie told People back in February.

“After we fell in love, we would laugh about it all the time,” Otis continues. “He’d always pick on me that he knew my whole name, but I couldn’t remember his.”
