Chrissy Teigen ripped her 'butthole' while giving birth to daughter Luna

Chrissy Teigen "ripped her butthole" when she gave birth to her daughter Luna.

The 32-year-old model has admitted postpartum life is "90 per cent better" this time around with her second child Miles - who was born last week - because she didn't suffer from a perineal tear when she delivered him, unlike the agony she experienced when she pushed her little girl out naturally two years ago.

Taking to her Twitter account, Chrissy said: "I can confirm postpartum life is 90% better when you don't rip to your butthole. Baby boy: 1 point. Luna: 0 (sic)"

And their births weren't the only thing Chrissy has been comparing as she's started to notice that her children share the same "nose" - even though Miles is smaller.

She said: "Same nose! He is a few weeks early so he's litttttttle and makes the teeniest noises. We are in love. (sic)"

Chrissy and her husband John Legend announced the arrival of their little boy last week but, at the time, refused to divulge any details about his name.

Alongside baby bottle emojis, she wrote: "Somebody's herrrrrrre! (sic)"

The couple - who got married in 2013 - previously admitted that they have been concerned about how well their daughter Luna would adapt to having a sibling.

John said: "Luna's gonna be an issue. I think she'll probably have some growing pains because she's currently running the house right now. She's used to being the centre of everything right now so we'll see how she adjusts to sharing the spotlight."

But, despite their concerns, Chrissy couldn't wait to hold her little boy in her arms as she has found her second pregnancy to be somewhat of a struggle.

She said: "Your second pregnancy is harder because you have a kid already."

Whilst John, 39, added: "You have to divide your energy between raising a kid and carrying one as well."
