The actor shared the happy news during an appearance on ‘Good Morning America’ on Thursday.
Liam, after being congratulated by the hosts, said: “Thank you, we’re just really happy.” He added, “The last week I’ve had a birthday, my son has gone to school for the first time today, so it feels like a lot of firsts for me actually, which is great!”
It comes after Maya, 20, was spotted wearing a large diamond engagement ring on her finger.
The couple has been dating for two years following Liam’s split from Cheryl, with whom he shares son, Bear.
