On the same day that Jennifer Lopez avoided discussing her rumoured pregnancy on Good Morning America, the Glad singer has again shunned the topic of her clearly apparent baby bump on Tuesday’s taping of the Late Show with David Letterman.

However this time it was Letterman – who is famous for pressing touchy subjects with celebrities including Paris Hilton - that kept mum on the issue on Lopez’s rumoured pregnancy.

According to reports the host opted to focus on her mother Guadalupe, who Lopez claims raised her with tough love.

The 60-year-old host concluded the topic of children when he asked J.Lo if she would be a tough parent herself with the singer grinning in response.
