The gorgeous girlies held hands as they made their way into Neighbourhood restaurant in the city, no doubt turning a few heads as they went.
Actress Steph opted for a jaw-dropping LBD to compliment her new hair, while lingerie model Rhian teamed her bright red dress with matching, colour-pop lipstick.
We're also loving how Hollyoaks star Steph seems to have co-ordinated her red nails with 28-year-old Rhian's dress.
Top marks ladies!
The girls hit the town on Saturday (21 March) and clearly had a great night out.
Steph, 37, shared a snap of the duo on Twitter and said: "Thank you @Neighbourhood4 for a lovely meal."
Obvs Steph loves the Manchester venue because this was her second visit this month! Earlier in March she debuted her lighter locks there during co-star Stephanie Davies' birthday party.
And the girls must have had fun on this latest visit because by Sunday morning Rhian, who appeared on Celebrity Big Brother in 2012, was feeling a little jaded.
She asked her Twitter followers: "Any suggestions for a nice lunch in Manchester today?.... Mind blank. Hangover brain."
Ouch. We hope you found somewhere to carb-load, Rhian!
