Christina Aguilera is having a ''blissful'' pregnancy.

The 'Your Body' hitmaker, who recently announced she is expecting her second child later this year, appears to be feeling very energetic as she is also working on her upcoming album.

The 33-year-old star wrote on Twitter: ''So blissful in taking this time for creating all things blossoming new on the horizon...album, baby & beautiful music to come.''

The blonde beauty is set to give birth to a baby girl and the tot will be her first child with fiancée Matthew Rutler.

The 'The Voice' USA mentor already has a six-year-old son with her ex-husband, Jordan Bratman and will take next season off from the NBC series to focus on her family.

Christina announced she was expecting in February, a week after Matthew proposed.

A source previously said: ''It wasn't expected, but it also wasn't unwelcome. They are all very excited though! Christina loves being a mom.''

The couple met on the set of movie 'Burlesque' in 2010 while the Grammy Award-winning singer was going through her divorce.

Production assistant Matthew popped the question in the backyard of their new home in Los Angeles, which is still under construction, on Valentine's Day (14.02.14).

Christina was said to be completely ''shocked'' by Matthew's romantic sunset proposal, for which he wore a suit and filled a gazebo with candles and red roses, before taking her to celebrate with friends and family.
