Have Beyoncé and Jay-Z finally chosen names for their twins?

Beyoncé and Jay-Z have reportedly chosen names for their twin babies, who are thought to have arrived in June.

The speculation comes after the couple filed trademarks on the names Rumi Carter and Sir Carter, just as they did with the name Blue Ivy after the birth of their now five-year-old daughter in 2012.

While there has been no official confirmation from the pair, sources say the twins arrived either Monday 12th or Tuesday 14th June in a LA hospital, with the couple welcoming one boy and one girl.

'Bey and Jay are thrilled and have started sharing the news with their family and closest friends,' an insider told People magazine at the time.

Beyoncé's father Mathew Knowles later appeared to verify the news with a post on his Twitter account, writing: 'They're here! #beyonce #twins #jayz #happybirthday' and sharing a picture of birthday balloons wishing the new arrivals a happy birthday from their granddad.

Beyoncé confirmed that she was expecting two new additions to the Carter family back in February 2017, when she shared a picture of herself knelt in front of a wall of flowers and cradling her growing bump to her Instagram account.

'We would like to share our love and happiness. We have been blessed two times over. We are incredibly grateful that our family will be growing by two, and we thank you for your well wishes. - The Carters,' she wrote alongside the picture, which has since been liked more than ten million times.

The couple are already parents to daughter Blue Ivy, whom they welcomed in January 2012.

At the time, it was reported that their unusual choice of baby name was a combination of producer Jay-Z's Blueprint albums, and Ivy representing the Roman numeral for four (IV), which is Beyoncé's lucky number, as it marks the day that of the month that she, her husband and her mother were all born, as well as the pair's wedding anniversary.

In 2016, the singer told ELLE magazine of her hopes for her daughter: 'I think just like any mother, I just want my child to be happy and healthy and have the opportunity to realize her dreams.'
