The TV personality congratulated his team for getting through to the Europa League semi-finals on Thursday, but focused specifically on one man who got on the scoresheet.
Bowen - who is in a relationship with Dyer's daughter, former Love Island contestant Dani - netted West Ham's third goal in their 3-0 win over Lyon.
And the Football Factory actor grabbed the opportunity to bring up the Hammers fans' viral song about the pair's romance, despite it being rather inappropriate…
Best known in football for Wigan's rendition for striker Will Grigg, the West Ham faithful created their own version of Drenchill's 1990s classic 'Freed From Desire' for their star winger and his new partner.
However, Dyer's new edition of the chant is slightly more PG…
The former EastEnders star posted a picture of Bowen after scoring his 48th minute goal, but it was the caption that stole the show.
"@jarrodbowen is on fire….and he's….cuddling me daughter or something," Dyer wrote.
"So proud. What a f****** night. Love to all the West Ham family."
The couple have both replied to the hilarious post, too.
The Hammers goal scorer commented multiple laughing emojis whilst his girlfriend, Dani, put "Ffs" along with some laughing emojis, too.
This isn't the first time the Hammers fan has boasted about the new edition to his family, either.
Posting a picture of the pair back at the beginning of December, Dyer put: "If Carlsberg made son in laws…"
Playing for the boyhood team of your new girlfriend's father - that's one way to win him over…
