But if there's anyone who can relate, it's Katie Price- also mother-of-five.
Katie, 37, whose marriage to third husband Kieran Hayler is going strong after they worked through his infidelity, has been 35-year-old Kerry Katona's rock.
Over the weekend Kerry secured her status as an independent woman, tweeting:
"I am a single mum who doesn't need a man to make her laugh, wipe her tears, hug her tight, see her succeed, watch her fail, or cheer her on to make her strong. My kids do (that)".
Katie Price responded to Kerry's stand, writing:
"My gorgeous girl".
And Kerry's inspirational quotes didn't end there.
The Atomic Kitten star embraced Monday morning, tweeting:
"Be strong enough to know when to let go and patient enough to wait for the things you deserve! Happy Monday all".
Kerry Katona is mother to Molly, 14, Lily-Sue, 12, from her marriage to Westlife's Brian McFadden, Heidi, eight, and seven-year-old Max from her marriage to cabbie Mark Croft, and baby DJ from her marriage to George.
Her relationship with George broke down around the time 35-year-old George Kay was reportedly arrested in connection with an assault on the singer.
A spokesperson for the Atomic Kitten singer said last month: “It is with deep sadness that Kerry announces the end of her marriage to George Kay. Her focus now will be on her gorgeous children.”
