Beyoncé Knowles-Carter made a rare public statement about her elusive son Sir Carter while bringing her $168.5M-grossing, 32-date Cowboy Carter World Tour to North London's Tottenham district on Thursday.

In fan footage uploaded on X, the 43-year-old pop diva wished little Sir and his fraternal twin sister Rumi Carter a happy eighth birthday while onstage at Tottenham Hotspur Stadium.

'Everybody say happy birthday, Rumi!' Beyoncé commanded her devoted Beyhive.

At that, Knowles-Carter's 13-year-old daughter Blue Ivy Carter affectionately touched her little sister on the chin during the three-hour concert featuring over 35 songs.

'Say happy birthday, Sir!' the 35-time Grammy winner added as Rumi embraced her. 'Mommy loves you.'

Blue Ivy serves back-up dancer duties on tour while Rumi has been making an appearance onstage each night of Beyoncé's tour beginning at SoFi Stadium in Inglewood, CA on April 28.

Last year, Rumi made her musical debut on the track Protector off Knowles-Carter's eighth studio album where she's heard asking: 'Mom, can I hear the lullaby please?'

Queen Bey and her husband of 17 years - Jay-Z (born Shawn Carter) - rarely discuss their only son.

'Rumi is amazing — an amazing artist, painter and creator,' proud grandmother Tina Knowles gushed to E! News last year.

'How could they be anything else growing up in that environment? All we talk about is creativity and fashion. Sir is very quiet. [He] does all of the numbers stuff, so he's not into fashion as much.'

On March 18, disgraced rapper-designer Kanye 'Ye' West questioned the twins' mental capacity in a shocking tweet that he deleted hours later 'because there was a possibility of my Twitter being cancelled.'

On February 2, Cowboy Carter won three Grammy Awards - album of the year, best country album, and best country duo/group performance for II Most Wanted with Miley Cyrus.

'I just feel very full and very honored. It's been many, many years. Just want to thank the Grammys, every songwriter, every collaborator, every producer, all of the hard work,' Beyoncé said in her acceptance speech.

'I want to dedicate this to Ms Martell, and I hope we just keep pushing forward. Opening doors. God bless y'all. Thank you so much. Thank you.'

On September 26, Knowles-Carter lost all 12 trophies she was nominated for her eighth studio album at the 2024 People's Choice Country Awards.

This, after the Texas Hold 'Em singer - who gets 58.7M monthly listeners on Spotify - shockingly received zero nominations at the 58th Annual Country Music Association Awards.

And while country music industry elites went out of their way to snub her, Beyoncé's Cowboy Carter became her eighth consecutive No. 1 album on the Billboard 200 and the first album by a black woman to top the Top Country Albums chart.

Knowles-Carter's first foray into the genre also scored her No. 1 records in the UK, Australia, Canada, France, Germany, and the Netherlands.

The Oscar-nominated songwriter is scheduled to continue her six-night stand at the Tottenham Hotspur Stadium this Saturday.
