Christina Aguilera has defended her late night partying.

The 'Dirrty' singer - who gave birth to son Max Liron in January - says she
is entitled to go out and enjoy herself with husband Jordan Bratman despite
being a mother.

She said: "I spend all day with my son and once in a while if I want to go
out and have a mommy-daddy night with my husband, I am more than allowed to
do that.

"They never air footage of the paparazzi actually pulling up beside my
husband and being like: 'When is she going to leave the house? I have been
trying to get a picture of her for weeks'.

"Everybody has an opinion and everybody sometimes wants to cause drama and
be mean spirited, but it's something that comes with what you do and I
learned that very early on."

Christina hit Las Vegas' Pure nightclub at Caesars Palace on Saturday
(05.31.08) for the launch of the jewelery line inspired by her, the Stephen
Webster Silver Collection.

The star also commented on the attention her post-baby breasts have
attracted.

She added to 'Access Hollywood': "It's funny, me and my husband
crack up about the bra sizes that we have been through since the pregnancy
and delivery. It's nuts to know what the female body's capable of."
