The social media star also included fellow TikToker Grace Keeling on her list of potential rivals.
Astrid called them out in a video which shows her practising her punches on a beach in a bikini.
The video had the caption: “Warming up to box Katie Price, Alexia Grace and GK Barry.
“Who wants the title fight?”
It comes after she was crowned the first female Misfits champion by beating Love Island star AJ Bunker.
After the fight with Bunker, Astrid was left with heavy bruising but now appears keen to get back in the ring.
Astrid has a record of two wins from two, as she also beat Keeley Colbran back in October.
Katie Price would be one of the biggest names to take part in the social media boxing circuit if she were to accept the challenge.
However, at KSI’s boxing event in January, Katie did make a comment suggesting she would be up for a fight at some point.
She was asked if she was going to fight that evening.
Katie replied: “I’ll tell you what, if you want me to fight someone… bring it on sunshine!”
Alexia, who earns £40,000 per month from OnlyFans, used to work as cabin crew before her change of career.
She is expected to fight Beth Fiit – another TikTok and OnlyFans star – to “squash their beef” that started at the beginning of the year.
Their rivalry started as Beth accused Alexia of copying her content with the former friends agreeing to a fight.
While Grace Keeling has a massive TikTok following of over three million fans.
She rose to fame during the first UK lockdown in 2020.
Grace posts short vlogs and stories showcasing her day-to-day life and has launched her very own named The Saving Grace Podcast.
