Hunter Johnson‘s dad wants to make sure the 14-year-old is the father of Bella Vaughn‘s one-year-old son Wesley.

The Ashley can reveal that, on Tuesday, an Arkansas judge issued an order for paternity testing to be done on Hunter, Bella and their son Wes. The order comes at the request of Hunter’s dad, Casey Johnson, who currently has temporary emergency custody of the teen. Casey is also fighting Bella’s mom Falen for full custody of baby Wesley.

The court order demands that the teen parents and baby Wesley all provide a sample to undergo blood grouping tests. (It’s interesting that the court ordered blood grouping tests rather than a DNA test. According to Britannica, “blood group studies cannot be used to prove paternity, [but] can provide unequivocal evidence that a male is not the father of a particular child.”)

Hunter, Bella and Wes have seven days from Tuesday to submit to the tests, and Casey has offered to foot the bill (and least for now) for the testing to be done.

As ‘Unexpected’ fans are aware, Hunter was only 12 years old when Wes was conceived, while Bella was 14. While the couple has never appeared to have any question that Hunter is the father of Wes, it seems that Casey does have some doubts. 

In his original filing for custody of Wes last month, Casey named Hunter as Wesley’s biological father but noted that paternity has not been “legally established.”

This is not the only legal action that Casey has taken this week in his bid for custody of Wes. On Monday, he filed to ask the court to appoint an attorney ad litem for Wesley. (An attorney ad litem is a lawyer who is appointed by the court to specifically represent the best interest of the child in the case, not the parents.) 

Casey asked for a specific attorney, and stated that all parties should be responsible for covering the costs of the attorney ad litem equally. The judge has not yet ruled on that particular motion.

As The Ashley previously reported, Bella announced on Tuesday that she and 14-year-old Hunter are now officially engaged.
