Justin Timberlake and Jessica Biel expecting a baby girl? Couple 'getting everything set for their little princess'

Justin Timberlake and Jessica Biel are reportedly going to welcome a baby girl.

According to a report in Life & Style, the couple are extremely excited about the news.

"They couldn't be more thrilled," a source told the publication. "Jessica's getting everything set for their little princess."

Biel and Timberlake who tied the knot in Southern Italy in October 2012, are already designing the nursery in their Los Angeles home.

"She and Justin agreed on a jungle theme," the insider added. "They don't want frills or anything too feminine, so they commissioned an artist to paint the walls with wild animals, like elephants, zebras and monkeys."

"He's going to get his little girl a drum set and a guitar, because he wants her to share his passion for music," the source said.

Rumours that the 32-year-old actress is pregnant started after she was spotted in Los Angeles on 22 October, trying to keep her stomach covered by an over-sized scarf.

In December, the 33-year-old actor's former 'N Sync bandmate Joey Fatone confirmed that the couple are expecting a baby during an interview with InTouch.

Last May, the Friends With Benefits actor had talked about having children.

''I'm not against the idea at all, but I think I still have some time ahead of me," he told OK! magazine, as quoted by EntertainmentWise. "Let's leave it to fate. Life didn't change overnight. Marriage, family - it's all part of the normal steps you take when you reach your thirties."

"She's brought me stability and an inner force," he said of Biel. "The most important thing for me is that we're able to communicate so well and talk about absolutely everything. It's beautiful to have that kind of closeness and understanding."
