The meaning behind "Toxic". Is it about a toxic relationship with an Irish Supervet?

[Jamie Lynn Forever]

I just came across an interesting article published in 2019. Apparently Cathy Dennis wrote the song when she was dating Noel Fitzpatrick, an Irish veterinary surgeon and the relationship ended during the year that "Toxic", co-written by Dennis, was recorded.

A 2019 article published in The Irish Times speculated that Fitzpatrick may be the subject of the song.

During the ad break I remember that Supervet is quite possibly the subject of Britney Spears’s pop song Toxic. I’m not joking. This song was co-written by former pop star Cathy Dennis who once dated Supervet and broke up with him in 2003, the same year the song was composed. I know! Yes, the Laois Lothario goes deeper into the culture than we hitherto thought. What else could be true? Did Rod Hull and Emu inspire Beyonce’s Crazy in Love? Was Dermot Bannon the spur that caused Justin Timberlake to Bring **** Back?

As a pop culture journalist I feel obliged to say, “Probably.”

But it raises troubling questions too. Is a kiss from Fitzpatrick’s lips truly as “toxic”, as Britney claimed? I imagine it’s some form of misunderstanding and that Cathy Dennis had been heedlessly mucking around with some of the medicines Noel was using to cure sick kittens. If so, that was deeply irresponsible and not Supervet’s fault. “That’s on you, Dennis,” I conclude. “Stop spreading these vile slurs, Spears!”

Discuss!

It was obvious that Cathy was referring to this but for Britney was perfect, I have always believed that she had a toxic relationship with Justin because of his attitude when they broke up.
