Kris Jenner works out at 4am.

The 59-year-old matriarch is delighted with all the attention she has received recently for her toned physique, but admits she has to work hard to stay in shape.

She said: ''All the attention I've received for my body recently is incredibly flattering. I feel like I'm 35 again!

''I work out every day but I'm so busy with work I have to get up at 4am to fit a session in.

''I'm such a foodie and I love my wine - I need to stay active to burn it all off.''

And Kris is thankful for the support of her boyfriend Corey Gamble as he gives her the motivation to work hard on herself and boosts her confidence.

She told Closer magazine: ''Corey certainly keeps me on my toes and is incredibly supportive.

''He gives me constant confidence boosts and is always telling me how great I look and how sexy I am, even if I'm having an off day.

''He's also a great motivation, as he's always in the gym and we often work out together.''
