Harper Beckham pens sweet tritbute to brother Romeo on his 24th birthday

Harper Beckham has nothing but all love for her older brother Romeo as she marked his 24th birthday. 

The youngest child of Victoria and David shared a loving tribute to her supporting brother on Instagram, on Sunday, following her parents' gushing posts about their son.

Harper, 15, used Romeo's birthday to tell him how 'lucky' she is 'to have you as my brother' as she uploaded a selfie with him.

'Today is all about celebrating you, and I hope you know how loved and appreciated you are,' Harper told Romeo. 'You'll always be one of the biggest role models in my life, and I'll forever look up to you and everything you are.'

'I'm so lucky to have you as my brother, and I genuinely don't know what I'd do without you.''Thank you for always being someone I can look up to and be proud of. I hope this year brings you so much happiness, love, and everything you've been wishing for, because you truly deserve it all.'

Proud Posh reposted the sweet message, admitting 'this melts my heart'.

Harper is close with both Romeo and brother Cruz.

On Saturday she joined Victoria and David to watch Cruz, 21, perform with his band The Breakers at Reading Festival after spending the summer with the family on board the Beckhams' superyacht.
