His girlfriend is gorgeous brunette Andriani Michael, 25, who also happens to be the daughter of his barber! It looks like Jack gave her a 25th birthday to remember, as he surprised her at her birthday party by getting down on one knee.
The excited sports star shared the news with family, fans and followers on his Instagram account saying, 'This weekend the beautiful @andriani_m made me the luckiest man in the world and said yes! Couldn't be happier... love you fiancée.'
In the sweet snap, the couple can be seen looking loved up, arms round each other. And Andriani's ring can just about be made out - from what we can tell it's a real sparkler!
Congratulations were quick to poor in with hundreds of fans wishing the couple well on the photo.
The pair are thought to have started dating around last summer, following Jack's split from his previous girlfriend Lauren Neal. Lauren and Jack have two children together from their relationship, Archie, three, and Delilah, one.
The proud dad often shares sweet snaps of his little ones on social media and isn't shy about praising his partner Andriani either. At New Year he posted a snap of Archie and Delilah along with the caption, 'Looking forward to 2016, even though ideally in 2015 I would have played more football, I still had a great year with all my friends and family and the amazing @andriani_m ❤️ hoping for more of the same with a little more football 😀⚽️ happy new year to you all!! Be the best you can!!'
Late last year he also gave fans a glimpse into his relationship, hinting that his wife-to-be is supportive and strong when things get tough. After an injury Jack uploaded a picture of the pair along with a caption, 'She's keeping me going ❤️❤ ️Hopefully be back soon Gooners to help the team! I miss you all 😔❤️'
Jack, who plays for Arsenal, has had rather a busy week as it has been announced that he's made his way onto Roy Hodgson's 26-man team to play in the European Championship for England, in France this summer.
What lovely news. Now for the wedding...
