The 'Can You Ever Forgive Me?' actress - who has Vivian, 11, and Georgette, eight, with her husband Ben Falcone - is delighted the youngsters have developed a passion for sport but she gets so "crazy" and excited, she's prone to bursting into tears and yelling at the other players while watching on the sidelines.

She said: "They're both really into basketball, which I love, it has taken over the house, I didn't see that one coming.

"They really like it and they both clicked in. When Georgie started, they explained guarding and she was like 'Got it!' She guarded their team, her own team, she was like 'No, no, no,' in their face...

"She made her first basket two weeks ago and... we all went crazy, my dad burst out crying, I burst out crying and there was a woman behind us going 'I don't know why I'm crying.'

"Something has happened, I scream and I yell like I've lost my mind,

"I've become exactly the person I always feared I would meet, a constant litany of 'Get it! Take It! Get It!' Once I was like, 'She doesn't deserve it!' Oh my God, I'm yelling at an eight year old!

"I finally stop and I'm shaking, like, I've got to walk it off.

"I'm so excited because I love watching girls that age become - not more aggressive, I don't mean it in a negative way - but seeing them go from 'I can take that ball' because they start off so polite, so when they start grabbing the ball, every aggressive part of me, that's like 96% of my being is like 'Take it from her!'

" I'm becoming a monster."

Melissa is nominated for an Oscar for her role in 'Can You Ever Forgive Me?' but joked her kids didn't let her get too excited when she got the early morning call confirming her place on the Best Actress shortlist.

Speaking on 'The Ellen DeGeneres Show', she quipped: "I was on the phone and they came downstairs and were like 'Is the toast ready?' There's no possible way to get overly impressed with myself in my house.
