Jenna Dewan-Tatum wants to wear maternity jeans after she's given birth - because they're so comfortable.

The 'Step Up' star is expecting her first child with husband Channing Tatum and one of her favourite things so far has been slipping into a nice roomy pair of denim pants.

She wrote on her Twitter page: ''I just might forever wear my maternity jeans. These things are so comfortable!! Thank you @JBrandJeans Paige denim and citizens of humanity (sic)''

Jenna is currently living in London with her hunky spouse and their baby will be born in the UK because Channing won't finish shooting in time to for the birth to take place in the US.

The 32-year-old actress has been spending her time watching music videos while Channing, 32, is on set and her favourite promo is 'Mirrors' by Justin Timberlake.

She tweeted: ''Leave it to @jtimberlake to bring back the art of music videos ... just saw the Mirrors video it was amazeballs. Yep amazeballs. Wow. And thanks to the UK for actually playing videos on tv!! (sic)''

The couple made the decision to have their baby in London because Jenna didn't want to take the risk that Channing might miss the birth.

The actor previously said: ''We're having the baby in London. I'm shooting there at the time. No downtime whatsoever.''
