Last week, Kylie Jenner and boyfriend rapper Travis Scott welcomed their beautiful baby daughter, Stormi Webster, and announced the 'surprise' birth of their newborn to the world via Instagram.
However, while the Kardashian, Jenner and Scott families (as well as the rest of the world) rejoiced in the birth of yet another social media icon (a snap of the little girl has become the most 'liked' image on Instagram ever), it sounds like Kylie's ex, Tyga, isn't joining in with the jubilation.
According to a Radar Online report published earlier this week, the 20-year-old's ex-boyfriend Tyga is demanding a paternity test as its rumoured he believes Stormi might be his daughter and not Scott's.
A source told the publication: 'Tyga wants a DNA test because he really thinks that there is a chance this baby could be his.'
Kylie and Tyga reportedly ended their relationship in April 2017 after three years of dating.
That same month, Kylie and Travis sparked romance rumours after being spotted together at a Coachella party before spending the weekend together in Boston later in the month.
'Tyga told friends that he was still sexually active with Kylie nine months ago, when this baby was likely conceived,' the source revealed.
On Monday, a source told Hollywood Life that the rapper - who shares a son with Blac Chyna, King - misses Kylie and 'wants to meet the baby'.
'He has a lot of questions and most importantly he still wonders if there is a chance if that baby could be his. Tyga misses Kylie now more than ever, really wants to meet the baby and wants some clarity and or closure on their situation,' added there source.
If Stormi is Tyga's daughter, he reportedly 'wants to know for sure so he can man-up and be a good father, or try to move on once and for all'.
In September 2017, Tyga posted (and then deleted) a Snapchat post where he claimed Ky's baby is 'my kid'.
News of a paternity test comes days after it was revealed Travis Scott has pleaded guilty to disorderly conduct for his behaviour at a concert in Arkansas.
Is there trouble in paradise already for the new family?
