Romeo and Cruz Beckham step out in their SLIPPERS as the brothers grab smoothies together in Notting Hill

Romeo Beckham and his brother Cruz both opted for an unusual choice in footwear on Monday, as they stepped out for a smoothie in London’s Notting Hill.

Romeo, 22, commanded attention as he strolled back to their car wearing an eye-matching pair of bright yellow slippers decorated with smiley faces.

He teamed the bizarre shoes with an understated black hoodie and oversized grey sweatpants, hiding his face beneath a baseball cap.

While Cruz, 20, also opted for slippers for the outing, sporting a pair of more on-trend platform UGGs, adorned with embroidered cartoon characters.

He cut a casual figure in black jogging bottoms, a knitted beanie and a blue jumper emblazoned with a photo of The Beatles.

Cruz’s appreciation for the iconic band goes far beyond clothing, as he is currently getting ready to release a debut single about wanting to be John Lennon.

The youngest son of David and Victoria Beckham is on the brink of launching his music career and has been joining forces with British Indie legends.

Last week, he teased his upcoming music on his Instagram, as he shared a snippet of a song about his hero John.

He and his band were filmed jamming on stage when Cruz approached the mic and sang: ‘I wanna be John Lennon’.

The clip abruptly ended there with no further lyrics sung, though he offered further snippets of the instrumentals from the tune in addition to other pictures.

Cruz’s musical offerings appeared to go down very well with his Instagram followers, who were quick to share their words of encouragement in the comments.

He kickstarted his career when he was just 11 years old and the Beckham family are said to have spent a small ‘fortune’ to help him create his sound with top songwriters.

And now the budding musician has become pals with Kooks frontman, Luke Pritchard, according to the Sun.

Luke said he is eager to help Cruz ‘navigate’ his future career in music, telling the publication: ‘We started writing songs together and we’ve become mates.
