"A lot of people have asked what it's like to follow in Ken's footsteps, but as far as I am concerned he is following in mine when it comes to playing at Twickenham as I have already played there twice and won on both occasions. That's something he hasn't achieved yet," she said with cheeky grin.
Scarlets hooker Ken makes his first start for Wales in Warren Gatland's side to earn his third cap while little sister Vicky will earn her sixth cap in the second row when Wales Women take on England Women at the completion of the men's game.
In last weekend's round of RBS 6 Nations games, Wales Women played their home game at Cross Keys. After seeing Vicky figure prominently in Wales' comfortable 20-0 victory, father Delme stepped on the gas to Cardiff 30 minutes away to watch the men's match at the Millennium Stadium. However he arrived too late, to see his son come on and earn his second cap.
"We've always had great support from our parents - they've been so supportive and never chosen between Vic or myself," said Ken.
"My father last week went and watched Vic first and actually missed me coming on against Scotland because he was rushing over from Cross Keys. So this week we're saving them a bit of mileage."
The England Women v Wales Women game will be broadcast live on red button BBC from 6.15pm.
