The rugby ace got down on bended knee to ask Jessica - with whom he shares a daughter Indie - to be his wife as they holidayed with several other rugby teammates in Dubai.
"And I was beginning to think that knee couldn't bend," Jessica joked on Instagram, posting a photo of the couple with their baby daughter Indie.
Pal and girlfriend of Rob Kearney, Jess Redden, was clearly over the moon for the pair, and posted a sneaky snap to her Instagram story with the bride-to-be - who gave Jess's followers a glimpse of her beautiful new diamond.
The ring is a cushion cut square diamond with a halo setting, and perfectly complemented her beautiful diamond drop earrings.
"What a great way to end a week we will never forget with a fabulous crew of friends!" the bride-to-be wrote alongside her engagement announcement, with the hashtags #isaidyes and #engaged.
