Her relationships haven't always been the rosiest, having divorced and gone through an acrimonious divorce from her ex-husband Moses Kanene with allegations of spousal abuse aswell as infidelity claims
And when that marriage ended, she even moved on to have a healthy relationship with her ex-husband to the point of amicably co-parenting their son. A fact that was evidenced by Lillian Muli sending Moses Kanene a birthday message.
And now she is in a relationship with Jared Nevaton, a controversial business mogul so I think Lillian Muli is indeed in a pretty good position to give relationship advice. Which is precisely what she did, explain to her young sisters why they prefer bad boys to the nice guy.
