Christina Aguilera is trying to stick to a healthy diet during her pregnancy because she doesn't want to gain as much weight as she did when she was pregnant with her son Max.
'The Voice' USA coach reportedly gained 40 pounds while expecting her child Max - her six-year-old son with ex-husband Jordan Bratman - and is determined not to put on as much weight carrying this baby, her first baby with her fiancé Matthew Rutler.
A source told Life and Style Weekly magazine: "She is making much better choices and is adamant about staying healthy. She's telling everyone how vibrant and connected to her body she feels."
Christina had shed a lot of weight before getting pregnant and has so far been able to carry on with her healthy eating regime relatively easily.
Her man Matthew has also been doting on his pop star partner and getting her whatever she needs.
The insider added: "He's doting on her night and day and never leaves her side. He talks to the baby through her stomach - it's so cute."
One food Christina, 33, has developed an appetite for is blackened barbecued meats, a common craving among expectant ladies.
A source previously said: "The other day, she went nuts for a plate of blackened BBQ. She laughs about it, but she was also relieved when she found out this craving isn't all that strange."
