She has been engaged to musician Matthew Rutler since 2014.
 

And Christina Aguilera, 36, looked happy than ever as she enjoyed a family day out with her other half and her two children at the Underwood Family Farms on Saturday in Los Angeles.
 

The Ain't No Other Man songstress cut a casual figure as she picked pumpkins with her son Max, nine - from her relationship with ex Jordan Bratman - and daughter Summer Rain, three, who she welcomed with Matthew.
 

The Voice coach sported a playful loose-fitting white tee which had 'Good witch' emblazoned across it which complemented her black leggings and plaid shirt.
 

She covered her peroxide blonde locks with a simple blue baseball cap that feature 'LA' in red while her trademark tresses were twirled tightly into a curl.

The Fighter diva shielded her eyes from the Californian sun by wearing a pair of oversized shades while she carried a black leather backpack as she posed for a photo.

Complementing his other half, Matthew donned a double denim while their daughter Summer Rain look adorable in her pretty purple and black tee.

While her eldest Max looked ready for a fun-filled day out in his cute red T-shirt and navy shorts.  
 

Matthew and Christina first started dating after they met on the set of Christina's film Burlesque in 2010.
 

The couple got together shortly after she split from husband Jordan Bratman, who she shares son Max, nine, with. Christina and Matthew have one daughter together, Summer Rain, three.


 

In 2015, she opened up about her precious daughter, the kind of mother she hopes to be and how her hectic life has put her wedding plans on hold.
 

She told People: 'I want her to be surrounded by love and grow up feeling safe. That's something I didn't have when I was young and something I have been very vocal about providing for my children.
 

In recent times, the former Voice judge performed at a lavish £7.3m wedding in Cyprus, but was forced to move her planned beach performance indoors for fear of disturbing local turtles.
