The couple, who are parents to two-year-old daughter Sienna-Rae, confirmed they had separated last month after eight years of marriage.
"We're so amicable and we get on and we speak every day," Lucy told the Loose Women panel. "He comes round for a brew. We will maintain as mummy and daddy moving forward. At the minute, our focus is Sienna."
Talking about the split, she said: "I'm up and down, it's difficult but we're amicable and we're talking daily. We'll remain friends and I genuinely mean that, we still care for each other. We're still best mates, we'll never ever fall out.
"We've got Sienna and she's our focus and we want to just make sure that she remains happy. Also, we live down the road from each other so we see each other all the time."
Lucy also addressed rumours that she was romantically linked to her Doctors co-star, and former Hollyoaks actor Andy Moss.
"It's just absolute nonsense. The only time I cried on his shoulder was when we were filming. He only knew about me and Al separating like everybody else when we announced it. He's a brilliant actor and we work together and that's it really."
But Lucy said the rumours had been "hurtful", even though Alan knew there was no truth to it.
"It's hurtful," she said. "He [Alan] knows it's utter rubbish as well. It's hurtful dealing with what I'm dealing with personally to have to have that. And Andy, he didn't ask to get involved in this."
Alan, who plays Tyrone Dobbs in Coronation Street, met Lucy, who played Katy Harris at the time, on the set of ITV soap in 2005 before marrying four years later.
Wild At Heart star Lucy is now starring in BBC's Doctors. Talking about returning to work, Lucy added: "The balance was brilliant. Priorities change and it took me a long time to find my feet and think 'yeah I want to go back to work'. It was harder for me, it wasn't for Sienna."
