Natalie Portman wrapped her baby

Precious: Natalie Portman wrapped her baby Adelph up in swaddle cloth as she made her way around Paris, yesterday

She only just introduced her baby boy Adelp to the world yesterday, after stepping out with the newborn bundle of joy in Paris.

And Natalie Portman was once again out and about with her infant son as she made her way around the French capital.

The 30-year-old Black Swan star wrapped her precious cargo up in patterned swaddle cloth, making sure to shield the little one from the cooler climate.

Once again the star dressed casually in a pair of denim jeans, a loose fitting plaid shirt and a comfortable pair of flat s for her day out.

The make-up free actress looked a little on the tired side, no doubt a result from being busy with her baby boy.

Natalie and her fiancé Benjamin Millepied were seen out with their baby son Aleph for the very first time, on Wednesday.

Natalie and her future husband Benjamin met on the set of the film Black Swan, on which Benjamin was the lead choreographer and Natalie's dance partner.

When she accepted her Best Actress Oscar earlier this year, she paid tribute to her French husband-to-be, saying: 'My beautiful love, Benjamin, who has now given me my most important role of my life.'
