The newlyweds and soon-to-be parents were spotted making their way into the Soho Sanctum Hotel on Tuesday evening (15 July) for Singer/Songwriter Mike Hough's 'Lost In Love' launch party.
Dancer Chloe showed off her blooming baby bump in a black jumpsuit with a gold chain pattern, while JB looked dapper in a waistcoat, white shirt and jeans.
It's been a busy few months for the loved-up couple, who tied the knot in front of friends and family at Mount Stuart country house on the Isle of Bute in May.
Then a month later, JB and Chloe announced they were expecting their first child together in a sweet photo showing JB kissing Chloe's baby bump.
JB - real name Jonathan Benjamin - has been trying to prepare himself for being a first-time dad, and it looks like he's been getting tips from former bandmate Marvin Humes!
Marvin and wife Rochelle became first time parents after welcoming daughter Alaia-Mai on 20 May last year, and this week, JB revealed that Marvin has advised him to read an essential book for new dads.
JB wrote on Instagram: "This is proving to be a life saver right now...thanks @marvinhumes #notlongtogo #eeek x."
It seems Chloe is taking pregnancy well too, telling fans last weekend (7 July): "That moment when your belly unknowingly becomes your table!! #easylife #freshego."
Viewers have recently seen JB compete on BBC One cookery show, Celebrity MasterChef, where he narrowly missed out on a spot in the final.
