Lovely news for the couple!

Congratulations are in order for actor David Arquette and his wife Christina, who've announced that they're expecting their second child together - a baby boy!

The 45-year-old Scream star and his wife of over a year took to their social media accounts to share the exciting news, giving their two-year-old son Charlie a starring role in the adorable announcement.

David - who also has 12-year-old daughter Coco with ex-wife Courteney Cox - uploaded a sweet video of Charlie holding a picture of the baby scan.

David and Christina began dating in 2011, but had an on-off relationship until Christina fell pregnant with Charlie in 2013. The couple got engaged three months after welcoming their son, and were married less than a year later on 12 April 2015 in Los Angeles.

The news comes shortly after David tragically lost his sister Alexis Arquette, who'd been battling HIV for 29 years, just last month. He took to Twitter on 16th September to share a message about his sister, posting a photo of Alexis next to lyrics from the Rolling Stone's song, She's a Rainbow.

'She's like a rainbow,' he wrote in his tweet, followed by lyrics that read: 'She comes in colors. Everywhere she combs her hair. She's like a rainbow.'
