Days after George Clooney's mother revealed her son will be a 'great' Dad, she now may have let slip on the gender of her soon-to-be grandchildren.

Following in the footsteps of Beyoncé's father, Matthew Knowles, who may have revealed the gender of his daughter's twins earlier this week, Nina Clooney has reportedly told RadarOnline the Ocean's Eleven actor and his wife, Amal, are expecting one of each.

'Yes, a boy and a girl. That's what I've been told,' the 77-year-old revealed.

'How marvelous! My husband and I are extremely excited,' she added.

The two-time Oscar winner's proud mother was also said to have admitted she didn't know the names of her future children – 'that's George and Amal's department' –, but is happy to see her son catch up with his sister, Adelia, as a parent, who has a '20-year-old and a 25-year-old'.

Earlier this week, Clooney's mother reportedly told US Weekly of how her son and his human-rights lawyer wife revealed the news of Amal's pregnancy to the family.

She said: 'We were with them and they told us together. We were all together, and it was lovely.'

'It was just a personal moment,' she continued.

With an Academy Award-winning father and badass lawyer mother, we must admit, we're pretty jealous of the twin's family lineage.
