The 37-year-old beauty revealed her daughter's piercing via Instagram, posting a snap of her snuggling up with Penelope, while Kourtney also confirmed the lip ring was a gift from her younger sister Kim Kardashian West.

She captioned the eye-catching photo: "Our Oscar Sunday. Yes, that's a lip ring. Thanks @kimkardashian. (sic)"

In the snap, Kourtney - who also shares Mason, seven, and Reign, two, with her ex-partner Scott Disick - is seen wearing a white bathrobe as her daughter rests on her left shoulder.

Meanwhile, rumours have suggested Kourtney and Scott, 33, could be on the cusp of rekindling their turbulent romance.

However, a source recently claimed Kourtney is happily single for the time being.

The 'Keeping Up with the Kardashians' star is instead directing all of her energy towards her children, rather than her romantic life.

An insider explained: "Kourtney and Scott are not back together or even at the point of trying to make things work. Kourtney is happy being a parent right now and that is her number one interest right now.

"She's not interested in being in a relationship with anyone. [Kourtney and Scott] have a wonderful relationship and are doing an amazing job at being good friends for their kids. There is nothing more to it than that right now."

Despite this, Kourtney is pleased Scott has managed to curb his drinking and regain control of his life over recent months.

The source said: "Scott is in a great place right now. He has toned down his partying and has done a really good job of staying in control. Everyone is really proud of Scott for sticking to his word and calming down."
