The 36-year-old singer has sparked rumours she's expecting her third child with her husband Eric Johnson, with whom she already has daughter Maxwell, four, and three-year-old son Ace, after she was spotted trying to hide her burgeoning baby bump with an over-sized handbag as she made her way out of the airport in New York this week.

But it wasn't just her determination to conceal her swollen stomach that raised eyebrows as a source has told RadarOnline.com that she and Eric opted for an "unusually teetotal" date night in The Big Apple the following day as well.

However, news that the couple are expecting another little one won't come as too much of a surprise to their friends and family as the pair have reportedly been in "baby-making mode for months" in a bid to give their youngsters one more sibling.

And it seems the impending arrival will give the couple - who got married in 2014 - the chance to get close to one another again following rumours their relationship was on the rocks last Spring when Eric allegedly sought "companionship elsewhere."

A source said at the time: "Eric got close to one of the pair's three nannies, a pretty blonde, and they were chatting nonstop while little Ace rode on his dad's shoulders."

Meanwhile, the happy baby news has seemingly come at the right time as the family were struck down with sorrow earlier this year when Jessica's father Joe Simpson - who is also the parent of Ashlee Simpson - found out he was battling prostate cancer.

The 58-year-old photographer was diagnosed with the disease a couple of months ago and is currently recovering after an operation, which is believed to have gone well.

A source said recently: "He's feeling great now and is optimistic. He's felt so much love and support from his family and friends."
