Christina Aguilera has trouble losing weight

Christina Aguilera is reportedly trying hard to shift her excess weight.

The 30-year-old singer has been sporting a curvier figure of late and is said to be unhappy about the extra pounds shes carrying.

An insider told Life & Style that the American singer has tried everything to lose the weight including employing a personal trainer, dietician and even a hypnotist none of which has worked.

Christina hates her thunder thighs, the source told the publication.

The mother-of-one has yet to respond to jibes from her arch-nemesis Kelly Osbourne who cruelly dismissed claims by her co-star on E!s Fashion Police that Christina was a U.S. size 2-4.

I am a 2-4, Kelly said. That is not a 2-4. She called me fat for years. I was never that fat.

Christina has battled her weight before and won. She lost 40lbs after the birth of her baby Max back in 2008.

The singer seems to have gone off the rails after her divorce from husband Jordan Bratman and has not looked her glamorous best for a long time.

She has been dating budding musician Matthew Rutler for nearly a year.
