J-Lo and Marc Anthony touch down with a precious cargo - their baby twins

The family of four arrived in Zaventem via private jet, Jennifer emerging first cradling her daughter while Marc followed behind with the couple's son in tow.

Despite her precious cargo, the new mother didn't exactly choose practicality over glamour, stepping off the plane in towering heels.

Anthony previously discussed taking his four-month-olds on tour, saying: 'When I perform... they will inspire me.'

And added that he only has one backstage demand: 'I just need toys for the kids.'

The tour will move on to Spain after the Belgium show before finishing up in Italy on July 2nd.

Anthony is one of the most popular Latin singers of all time and has sold more than 10 million albums worldwide.

The singer and his wife have barely been apart since their marriage in 2004 and the couple enjoyed a joint tour together last year where Lopez announced her pregnancy.

He says his 38-year-old wife is revelling in her new role as a mother.

'She's such an amazing mom and I'm so proud of her. She's such a gem to watch.'

Still, she will soon return to work, and has a number of film projects lined up, including the romantic comedy, Love and Other Impossible Pursuits.
