The 25-year-old actress and her partner Alexander Wraith welcomed little Titan into the world on September 16, and now the

'Heroes Reborn' actress has shared her first picture of the tot on her Instagram account.

Francesca posted a photo of herself snuggled in bed with Titan, but all that could be seen of the baby was his head peeking up from the covers.

She simply captioned the photo with a contented face emoji.

Titan is Francesca's first child, while Alexander has seven-year-old Trajan with his estranged wife Lili Gaildraud, who he separated from in 2015.

The pair celebrated their new arrival in August with a baby shower, and confirmed his name would be Titan.

Francesca - whose father is Hollywood legend Clint Eastwood - confirmed at the 2018 Environmental Media Association Awards in May that she was expecting for the first time, and admitted she was "looking forward" to her future as a mother.

Alexander said in a statement: "Francesca and I are very happy and excited to announce that we are having a child together, we are looking forward to our future together."

Francesca's mother Frances Fisher said at the event: "I'm so excited. I'm gonna be a grandma."

The announcement came just days after Francesca's 21-year-old sister Morgan Eastwood cryptically shared an image of someone's baby bump on her Instagram Stories.

Francesca is said to have been dating 'Agents of S.H.I.E.L.D' actor Alexander for "some time".

He shared a Valentine's Day tribute to her on his Instagram in February.

Alexander wrote: "When all is said and done, more is always said than done. Happy V day, Be true to you and you."

In June, he shared a picture of Francesca lying on him and wrote: "Every beauty needs her beast to protect her from everything but him. (sic)"
