WATCH: Mzansi TikTok praises Rachel Kolisi for being a 'cool' mom

Just when we thought Rachel Kolisi couldn't get cooler, she just did!

The mom of two shared a TikTok video which has Mzansi praising her for being a 'cool' mother figure to Siya Kolisi's little sister, Liphelo or Pelo as she is affectionately called by her family and friends.

Siya Kolisi legally adopted his sister and brother, Liphelo and Liyema, after their mother died in 2009.

The back-to-back Springboks champion hadn’t seen his siblings in years before he finally found them in foster care in Zwide – a township in Gqeberha – and they have been together ever since.

Rachel Kolisi helps take care of his siblings along with their kids, Nicholas and Keziah.

In the video Rachel posted to her TikTok page, Liphelo asks her some 'hypothetical questions' such as 'what would you do if I came home drunk? What would you do if I called you at 3am from jail? What would you do if I came home with a tattoo?' 

Most of these questions would freak out some parents but not mama Rachel...

Rachel's answers are leaving Mzansi in their feels for being so 'sweet,' 'calming,' 'mindful' and 'heartwarming' as some TikTok users said in the comments. 

One TikTok user said: 'These questions are stressing Rachel but her answers are perfect. She’s not saying Pelo won’t get into trouble but at all times she’s prioritising her safety.'

Other TikTokers have asked Pelo to ask Siya these questions as well, but overall Rachel got the stamp of 'cool mom' approval from Mzansi Tok.
