She told the Telegraph's Stella magazine that was was "great" and Hugo was "great," then said: "I'm very happy, that's all I can say."
The couple have been enjoying the weekend at Glastonbury, and Hugo spoke to The Mirror about their relationship. He said: "This is my life, man. We're happy. People are going to assume what they want. We had something before which was very public, but we're both good."

As Millie's ex-husband, Professor Green, was also attending to festival, Hugo spoke about the possibility of bumping into him, saying: "It's a festival [it could happen]. But I don't know."
The couple were granted a quickie divorce back in May after announcing their split three months earlier. Although Millie cited the cause was for "unreasonable behaviour," the pair released a joint statement confirming that the break-up was "amicable." It read: "It is with sadness and regret that we confirm our separation. It is a mutual decision, we still care deeply about each other and would like it to be known that it is on amicable terms and we wish each other well."

The rapper also revealed to The Sun that the pair never saw each other as they were both so difficult, and it consequently caused difficulties in their marriage. He said: "We had seen each other like ships in the night, but we weren’t getting any quality time together. It is good sometimes to have space, but it is also difficult when you miss someone for that long. It used to happen when I was touring.
"You would have a day off and try and have the best day of your life, But then you’d just start arguing. That is a relationship. The best way is a balance and being really clever with the time you do have together and making the most of that."
