Singer-songwriter Rebecca wrapped up her headline tour at the Irish capital's Vicar Street venue on Sunday evening (13 April), just after sharing her happy baby news.
Rebecca took to the stage in a pretty flowing patterned gown that hid any hint of a possible baby bump.
Earlier in the day, an overjoyed Rebecca had announced her pregnancy via Twitter, telling fans: "Yes I am having a new lovely baby. Children are such a blessing and I'm grateful to god for my new little gift."
The star is already mum to Lillie May and Karl.
Last night, she admitted that she couldn't wait to get back home to her children after completing the final date on her tour. "Think I've fell a little in love with the irish i'll be back ;) , get to see my gorgeous babies today. So excited! Films, sweets and snuggles (sic)."
Rebecca's tour ended on a high with several concert-goers taking to Twitter to congratulate her on both the baby and a fabulous final show.
One fan wrote: "I had a great time in Dublin tonight!! What an amazing show!! Congratulations on your baby news!! Brilliant news xxx." Another said: "you were #amazing at vicar street Dublin last nite #suchashow#amazinglady #bestofluckwithyournewbaby."
Rebecca finished runner-up to Matt Cardle on the seventh series of X Factor but, like One Direction and JLS, she has shown you don't need to win the show to find success.
The 27-year-old released debut album Heaven in 2011, which featured the single 'Nothing's Real But Love'. Her second album, Freedom, was released in December 2013.
