Christina Aguilera feels "more confident" with her second child.
The 33-year-old singer, who gave birth to daughter Summer Rain in August with fiancé Matthew Rutler and has son, Max, six, with ex-husband Jordan Bratman, has reportedly been easing herself back into work recently, as her baby is very relaxed.
A source said: "She's definitely more confident the second time around with motherhood. The baby has been great."
The blonde beauty has already started shooting season eight of 'The Voice' USA, which will air next spring, and is also recording her next album.
Christina showed off her fit post-pregnancy figure at the Breakthrough Prize awards in Mountain View, California on Sunday night (09.11.14), but hasn't embarked on a drastic diet.
The insider told PEOPLE magazine: "Her focus is really happiness within. Her workouts consist ... of things that balance her mind, body and soul."
The 'Your Body' hitmaker got engaged to production assistant Matthew in February after almost four years of dating and the couple are rumoured to be planning to get married next month.
A source previously said: "They love Hawaii, where they got engaged, but Christina is worries about privacy, so they might rent a private island."
