Ciara and boyfriend Amar’e Stoudemire took their relationship into the fast lane yesterday as they took to the streets of Miami on a pair of matching mopeds.

The couple, who have been spotted soaking up the sun in recent days on the beach, looked the part in the casual clothes and shades as they zoomed around on the bumble-bee coloured bikes.

Rumours that Ciara is dating NBA star Stoudemire, 28, were apparently confirmed when he joined the singer for a romantic break this week.

The New York Knicks player was all eyes as the 25-year-old star sashayed around on Miami Beach, before taking a dip in the ocean.

Ciara, who also works as a model, showed off her action girl side as she pulled on a life vest for a spell on a jet ski.

The star recently revealed her secrets to staying in shape – namely that watching what you eat is more important than how much you exercise.

’85 percent of it is what you eat, and 15 percent of it is how you work out,’

She told Entertainment Tonight.

‘Dancing-however you do it, even if it’s in your living room – is a great workout.’

However, she admitted that she sometimes gives in to temptation.

‘Food is fun,’ she said. ‘I have moments when I want to eat pizza or a hamburger – I’m not going to drive myself crazy.’

Ciara’s sensible attitude to food and exercise has paid off, with her return to Maxim’s Hot 100 after four year’s absence.
