Megan McKenna has hinted she and Pete Wicks talked about "marriage and having babies" the day before they split-up.
The former "The Only Way Is Essex" star-turned-country singer appeared to share details of her intimate relationship as she sang about her heartbreak at her first London gig.
According to The Sun newspaper, Megan introduced her new track "History" by telling the sell-out crowd: "So you know when you're with someone and you talk about marriage and having babies and you get all excited ... then the next day it all ends."
The 25-year-old reality TV star split from her on/off boyfriend Pete, 28, earlier this year.
Megan - who topped the iTunes Download Chart with her debut single "High Heeled Shoes" - poured out her heart as she appeared at London nightclub Scala, confirming to the crowd: "Yes, I'm single."
The ex "TOWIE" star even joked about her famous temper tantrums on the ITV2 show, saying: "There's always ups and downs in relationships and I am made out to be the bad person, but I'm not.
"I'm really good in relationships.
"I may have a little meltdown ... but don't all boys and girls have meltdowns."
In revenge track "History", Megan sings: "How do you want me to fake a smile when I see you/Like I'm happy for you?
"I just can't seem to let it go and I know that you've moved on/We're done for good, we're history."
As the crowd cheered, Megan joked: "I need you all to back me up on "TOWIE". But I won't talk about that."
Megan also performed a Miley Cyrus medley, including "Wrecking Ball", and covered the Queen of Country Dolly Parton's hit "Jolene".
After the show Megan tweeted: "Such an amazing night!!!! Singing the one and only Dolly Parton hit Jolene! Such an unreal feeling and love seeing people enjoying it as much as I did!
