Spears pledges to continue career

Britney Spears says she'll never give up her career.

The singer denied claims she intends to be a stay-at-home mum.

Earlier this week she confirmed reports she is pregnant with her second child.

The star says her singing and dancing has a positive effect on her son Sean Preston.

"If mom's happy, baby's happy!" she reasoned.

She added that she's been meeting with different people to work on an album and is looking at different movie scripts.
