Jessica Biel is believed to be pregnant.

The 'Total Recall' star is reportedly expecting her first child with husband Justin Timberlake - who she married in October 2012 - and the couple are delighted.

A friend of the 32-year-old actress told Us Weekly magazine: ''Right now they are just enjoying the news for themselves.

''They just want a happy baby.''

The baby news may not shock their fans as in August this year, sources revealed the pair were trying to conceive.

A source said at the time: ''They've been trying to conceive for a couple of months now, and she told Justin she's going to see a fertility expert.

''She has no problem using technology, if that's what it will take to have a baby and stick this marriage out.''

The couple fuelled pregnancy rumours last week when the 33-year-old 'Mirrors' hitmaker showed up at the amfAR Gala in Los Angeles without his wife.

The rumours continued when Jessica's friend and InStyle editor, Ariel Foxman, shared a Throwback Thursday picture on Instagram last week, congratulating Jessica on her pregnancy.

He tweeted: ''Congrats @jessicabiel on your impending motherhood... Looking forward to the red carpet maternity style pic to come #tbt. (sic)''
