You'll need a tissue for this...
Tina Knowles Lawson on Beyoncé, Solange, Kelly Rowland and niece Angie.
The fashion designer and businesswoman is mother to Beyoncé, 33, and Solange Knowles, 28. She was married to their father Matthew Knowles for 31 years but the couple divorced in 2011 after it emerged that Matthew had an affair and fathered a child with actress Alexsandra White. Tina, 61, tied the knot with actor Richard Lawson, 68, in April this year. The above picture is from the ceremony.
On her support system
"I gave birth to two of you, but I have four incredible daughters.
"When I’m feeling sad or not-so-cute or maybe a little sorry for myself, and you all include me in your group chat and tell me how hot I still look or how cool I am. Maybe you send me a crazy YouTube video. What actually works best is a cute photo of my grandchildren.
"I remember slumber parties after my divorce, when we watched old movies and ate a lot of ice cream. I felt so loved and supported. The roles were reversed, and it was ME who needed nurturing."
On what the world doesn't realise about Beyoncé
"Beyoncé, I wish people could see how you are when you’re not in front of the camera or on the stage. How compassionate and kind you are to people, how you look them right in the eye when you speak to them. How hard you work, how generous you are with your time and money. How you don’t care if anyone knows about it because you do it from the heart....Yes, you are a huge star, but you have somehow managed to stay grounded and humble in the wake of all your success."
On why she admires Solange
"Solange, I knew when you were born three days late that you would walk to the beat of your own drum. You were always my rebel warrior! Always defending the underdog and fighting for what you believe in. I remember you, at 10 years old, started a petition to remove a bad teacher, and your dad and I were so proud of you. I love that you do not let others define who you are, or what you are. Whether in your music, fashion or your life, you truly are your own incredible, unapologetic person!"
On her most treasured memory
"I’m often asked, what was my most proud moment? I would have to say it was at my recent wedding, when all four of you said in your own words that I taught by example and that I helped to make you the women you are today!!!! That was truly my proudest moment!"
Victoria Beckham to Brooklyn, Cruz, Romeo and Harper
The designer, businesswoman and former Spice Girl is mother to Brooklyn, 16, Romeo, 12, Cruz, 10, and Harper, 3, with husband David Beckham.
On how much her children mean to her
"They are a wonder to me every day. From a teenage son through to a toddler daughter, each moment of every day is filled with different energies, activities, feelings and a lot of comedy. From playing sport to lounging on the sofa, each of my children fill every second with laughter, music and discussion. They are kind hearted and well-mannered and have incredibly enquiring minds, and I feel incredibly blessed to be surrounded by these phenomenal human beings."
On the values she hopes to teach her children
"Being in a position where they live such a privileged life, it is important that our children understand humility, that they appreciate how their parents have worked very hard to create this life for the family and that they, too, have a responsibility to work hard, be respectful and never, ever take anything for granted."
On missing her kids when she's away
"Like so many working mothers all over the world, I feel the constant struggle to be the best mother I can, whilst setting a good example to my children to work hard. I travel for work when it’s necessary, and I miss them all the time when I am away. But they hide notes in my suitcase, which I love to find when unpacking, and I always bring photographs of all the family and put them by my bed so they are the first thing I see when I wake up and the last thing I see when I go to sleep."
Sharon Osbourne to Aimee, Kelly and Jack
English television personality Sharon Osbourne, 62, and Rock singer Ozzy Osbourne, are parents to Aimee, 31, Kelly, 30 and Jack, 29.
On the fear of being a first time mum
"I had no experience. I never thought I would become a mom. None of my friends had children. So in the first couple weeks after you were born, Aimee, I was in shock, just panicked, thinking, “How do I take care of you? What am I meant to do?” Ozzie had two children with his first wife, so he was more equipped than I was. He was always very good after I breastfed, he would settle you down. But I was still overwhelmed."
On her unconditional love
"Jack and Kelly, you have overcome drugs and drinking, and Aimee, you’re pursuing your dreams. I’m so proud that you’ve all become such good, levelheaded people who care what goes on in the world. Success doesn’t mean shit to me. This entertainment industry doesn’t mean anything to me. If you do well and you’re strong—that’s what makes me feel happy, that’s what makes me feel great."
On her most treasured possessions
"When I think of you all, my heart just melts. People come into my home and they say it’s like a time capsule. Everything is covered in pictures and notes and paintings that I have framed. Every gift you ever gave me I still have, and they are most treasured. Necklaces and paintings and hearts for Mother’s Day and all those drawings, I have them framed everywhere. They are my family jewels."
