Christina Aguilera enjoyed an early birthday celebration at Disneyland.

The 'Your Body' hitmaker, who gave birth to her second child, Summer Rain, in August, was spotted strolling around the theme-park in Anaheim, California on Wednesday night (17.12.14) with fiancé Matthew Rutler and a large group of friends, one day before her 34th birthday.

The blonde beauty, who also has six-year-old son Max with ex-husband Jordan Bratman, donned a pair of Minnie Mouse ears for the occasion and was spotted nervously lining up for some of the attraction's rides, including the Space Mountain roller coaster.

The 'Voice' USA mentor decided to leave her children at home with a babysitter for the night, according to MailOnline.

Production assistant Matt, 29, held on to the singer's hand for much of the evening and they were also seen buying some merchandise at the gift shop.

Christina has kept a relatively low profile since welcoming her daughter into the world earlier this year, but recently returned to work on the next series of the reality singing competition after Gwen Stefani filled in for her on the panel this season.

Last month, the 'Baby Don't Lie' hitmaker admitted she was reluctant to hand the job back to Christina.

She said: ''I feel really jealous of Christina. I feel weird that they are doing it without me.''
