Antonio Banderas says Brad Pitt and Angelina Jolie should just "try their best" when they welcome their twins later this month.

The 'Shrek' actor — who has an 11-year-old daughter Stella and stepchildren Alexander, 23, and 18-year-old Dakota with wife Melanie Griffith — has advised the couple to make sure they are prepared for the impending arrivals.

He said: "I would just tell them: 'Try your best, man', because when the kids come to the house, they become the kids and you are not anymore!'"

Banderas — who co-starred with Pitt in 'Interview with the Vampire' in 1994 and Jolie in 'Original Sin' in 2001 — also said the couple are "very happy".

Speaking at the launch of his new fragrance Blue Seduction For Women, Antonio said: "I know both of them, they are my friends. They are very happy together."

Meanwhile, Banderas — who was nominated for a prestigious Tony award for his role in musical 'Nine' — recently revealed he is planning a return to New York's famous Broadway theatre district.

He said: "I am working with David Leveaux, who was the director of 'Nine', on that possibility. It will be 'Don Giovanni'."
