The TOWIE lovebirds couldn't hide their HUGE smiles when they visited ZSL London Zoo on a sunny Friday (10 April).
Wearing reflective Aviator sunglasses, Lydia shared a photo of herself infront of a tall giraffe at the famous zoo.
Alongside the picture, she wrote: "Such an amazing day with all the brothers and sisters. Celebrating the Easter holidays & the sunshine @zsllondonzoo."
Although there was no mention of Arg, her boyfriend and TOWIE co-star also told fans he was there.
Monkeying around as usual, Arg posted a picture of two funny-looking apes...
Taking the opportunity to wish Lydia's mum Debbie a happy birthday while she holidays in Venice, Arg said: "Happy birthday to my future mother in law haha @debbietowie We had a great time in @zls Hope your loving Venice! X"
Lydia also acknowledged her mum's special day on Twitter, by posting this very sweet message: "Happy Birthday to this very special lady. You give me such much determination, positivity and wisdom. Mother and Daughter by chance, best friends by choice. Love you with all my heart. X"
In the season finale of The Only Way Is Essex last Sunday (5 April), viewers saw Lydia and Arg reunite after months of heartache and troubles.
That weekend, they confirmed their renewed love to the world with a selfie from their shared bed.
Speaking on ITV's Lorraine this week, Lydia confessed: "After nearly seven years on and off, that's it, we're back together. [It's] as on as possibly it can be, yeah it's full on.
"This time for me, that's it."
