Christina Aguilera's fiancé Matt Rutler is receiving major backlash after he was spotted holding 18-month-old daughter Summer Rain in his lap while driving.

The 30-year-old father allegedly pulled over to the side of the road in Brentwood, Calif., and placed the toddler on his lap before driving approximately 100 yards into a parking space. Christina watched from the passenger seat.
