Kim Kardashian says learning to play the piano and baby-sitting her daughter, North West were the reasons she couldn't hit the 2015 Oscars red carpet, on February 22 in Los Angeles.

'Just finished my piano lesson in time to watch the Oscars' red carpet!!!' the 34-year-old tweeted, Sunday night.

The 34-year-old claimed she was struggling to practice one of her Kanye West's songs on Oscars night.The reality star told her 29 million, 'I'm going to surprise Kanye by learning one of his songs! He's hardly on social media so he won't know I'm tweeting this lol.'

That wasn't all. Her less than 2-year-old child was another reason Kim couldn't leave the house.

When asked by a Twitter user if she would be making an appearance, she responded: 'I have no one to watch North so we're watching together in our pi's! Next year for sure!'

However, it's hard to imagine why the $40 million worth fashion entrepreneur couldn't find a baby sitter for her 20-month-old daughter that night or did Kanye asked her to stay at home?.

Kim however sent some love to sister Khloe Kardashian, who was checking out the fashions for E!'s Live From The Red Carpet show with his Giuliana Rancic!

'Love watching @khloekardashian talking fashion on E's red carpet footage! KoKo looks so pretty!!!!' Kim tweeted about her younger sister who donned a strapless red gown with a demure knee-high split at the front for her gig.

She also complimented actress  'Wolf Of Wall Street' star, Margot Robbie on her new bob hairdo at the event, tweeting: 'Margot Robbie looks so gorge! She's my fave so far!!! #Oscars.'

Do you guys think Kim is telling the truth?
