"10% tougher, thanks to @kalula_tattoo. I am so in love with my pretty little lotus flower. Thank you so much you incredibly talented human!"
Last week, Richie, 31, fuelled speculation when he failed to deny break-up talk, as reported by The Daily Telegraph.
"A downcast Strahan danced around the issue and refused to shut down speculation that the couple had broken up," says the publication.
Meanwhile, Nation, 25, did not respond to calls for comment.
The long-distance couple recently took solo holidays to the same destination, another red flag according to the report: "the pair were due to travel to South East Asia together recently, instead they took separate holidays."
Tellingly, the reality stars have not appeared in each other's social media feeds. A stark contrast to the early days of their relationship.
Happier times, Nation, last posted a photo of her beau on April 25. As for Richie? His most recent couple shot is dated May 22.
