The 'Hunger Games' actor is so excited for wife Ashlee Simpson Ross, who already has six-year-old son Bronx with ex-husband Pete Wentz, to give birth to their first child together later this month.

The 26-year-old star, who is legendary singer Diana Ross' son, shared a number of pictures from the couple's wedding day and rehearsal dinner last August on Instagram, with the caption: "#reflections of such a beautiful wedding. Me and my amazing wife @ashleesimpsonross. At my mothers house in Greenwich Connecticut! And now I can't wait to meet my little baby girl. (sic)

"Look how beautiful our reception was!!! Just looking back through photos. Such a special day."

Alongside an image of them kissing, he also wrote: "Love those lips!!! #weddingmemories"

The couple, who announced Ashlee's pregnancy last December, recently celebrated the upcoming launch of Evan's debut album with friends and family in Malibu, where the actor gave the blonde beauty, 30, a limited-edition green Chanel Graffiti Messenger bag as an early push present.

A source recently told PEOPLE.com: "He brought it out to the deck and gave it to her in front of her family and friends. She was so surprised. Her dad Joe loved it and gave Evan a pat on the back."

The duo have already picked a name for their baby girl, but are keeping it a secret until after she is born.

Evan recently said: "It's unique. You guys will figure out the story behind it once we tell the name."
