Earlier this week, Richie, 32, shared another selfie with Alex with the caption: ‘Moments like this’.
Richie controversially picked Alex, 25, in the grand finale of season four of The Bachelor.
Confessing his love for the singe mum on Instagram, Richie wrote: ‘I found her, my love, my co-pilot, my partner in crime, my everything. I followed my heart and I've never been this happy. Alex to me you're perfect, you're everything I could of ever wished for. You make me the happiest guy in the world, I love you.
Thank you to my family, friends and everyone that supported us.
‘This has been a wild ride and we are looking forward to sharing our adventures to come.’
