Sharing a photo of the couple vacationing outside a marina, the UFC star wrote: “Happy birthday my sister @aoife.mcgregor, crazy style queen, love you so much, to the moon and back, for always and always, the world is yours, my blood.
Below the post, the birthday girl commented on some heart emojis and said, “FOREVER.”
It’s Aoife’s first trip around the sun since splitting from husband Mark Elliott last year.
Elliot confirmed to the Sunday World in August that his relationship with Aoife had broken down as he did not want to have any more children.
“It was basically to do with the kids – she wanted a baby and I didn’t,” said Mark, who has 20-year-old twin daughters from a previous relationship.
Months after their marriage broke up, Aoife paid “physical visits” to Kinahan Cartel criminal Graham “The Wig” Whelan at Portlaoise Jail.
The businesswoman, who has no involvement in crime and no criminal convictions, is said to have become close friends with the caged mobster after breaking up with Elliott.
The Sunday World has revealed how Aoife met Whelan, who is serving an 18 month sentence for money laundering, for the first time just before Christmas for their first physical visit since being locked up.
And in January, she reportedly spent just under an hour inside the high security prison with Whelan, who is also friends with Aoife’s brother Conor and a member of her Black pub football team. Forge.
But The Wig’s pub football days were suspended by the Special Criminal Court in November after it was learned he drunkenly bragged to Gardai about getting the €1,200 cash from ‘his Swiss roll’ during an arrest at the Intercontinental Hotel, Ballsbridge. , Dublin on 31 January 2019.
He also told detectives “I am a dangerous criminal” and to “find me”.
The court heard it was a reference to Whelan jailed for six years for a €1.6million drug bust at a Dublin city center hotel.
The infamous bust, performed at the Holiday Inn when Whelan was just 17, was seen as the start of the Crumlin/Drimnagh feud which led to the murder of 16 people.
After being caught, he told Gardai he could do 10 years in prison “standing on his head”.
Stemming from his arrest at the Intercontinental, Whelan pleaded guilty to participating in the actions of an organized crime gang by laundering money for the group.
He also admitted to being in possession of €1,200 in cash and a €28,000 Audemars Piguet Royal Oak gentleman’s watch, which turned out to be the proceeds of crime.
The special criminal court heard Whelan had 33 previous convictions, including the prison sentence served for the 1.6 million drug seizure, as well as violent disorder, criminal damage and assault causing damage.
