Scarlett Johansson has reportedly joked her baby gets starstruck around her.

The 30-year-old actress has two-month-old daughter Rose Dorothy with French journalist Romain Dauriac and she's said to have been overheard joking her newborn got starstruck by her appearance, like many of her fans.

A source - who heard Scarlett talking to a pal at the Gotham Awards on Monday (01.12.14) - told the New York Post newspaper's PageSix: ''Scarlett was saying how her daughter's eyes lit up when she saw her in full makeup and with her hair done for the event.''

The 'Avengers' star is also reported to have offered her sympathies to a fellow new mum who told the beauty about her struggle to keep her baby's food down.

The source added: ''The other mum was just smiling and talking about how her baby keeps puking on everything. Scarlett was just smiling and nodding with empathy.''

Meanwhile, it's been confirmed Scarlett and Romain - who have been dating for over two years - tied the knot shortly after the birth of their new daughter.

The Granite County Clerk of Philipsburg, Montana is said to have revealed that he married the couple during a small ceremony in the state on October 1.
