Luisa, who plays Tina Carter in the BBC One soap, announced her happy news via Twitter on Tuesday afternoon (21 July).
She said: "OMG we did it!!! We are officially WIFE & WIFE!!! @YeoAnnette I'm so excited to be spending the rest of my life with you."
Annette, who has been with Luisa for 15 years, also took to Twitter to mark the occasion.
"Thank you for making an honest woman of me at last," Annette tweeted. "It was worth the wait!"

Luisa and Annette entered into a civil partnership in 2006 and decided to marry following the legalisation of same-sex marriage in the UK.
The couple revealed last month that their two adopted teenage daughters would act as bridesmaids.
