She’s been busy topping up her tan during a romantic break with boyfriend Alex Rodriguez, 43.

And Jennifer Lopez ensured all eyes were on her as she soaked up the sun while on top of a luxury yacht in the Amalfi Coast in Italy on Thursday.

The esteemed star, 49, flaunted her famously peachy derriere in a skimpy grey work-out ensemble, with a plunging neckline also highlighting her ample cleavage.

J-Lo and Alex have been enjoying a romantic getaway in Italy, after a year and a half of romance.

Speaking on US talk show Today at the beginning of August, Alex said of the pair: ‘To be honest if this happened when we were in our twenties… it would have never happened.

‘It was just too much craziness, I wasn’t mature enough,’ he explained. ‘You know boys…. we gotta get our dumbness out of the way.’

‘We’re both in our 40s, we’re both from New York, we both come from Latino backgrounds, we both have two kids,’ he added. ‘I think we’ve both been through a lot and can really appreciate each other… both the good and the challenges.’

No wedding bells: sources have since claimed the pair are in no rush to walk down the aisle, telling Us Weekly: ‘They were ready to get married early on and talked about it’

The duo went on to spark engagement rumours last month, when Jennifer was pictured wearing a ring given to her by her beau.

She shared a snap of herself and Rodriguez enjoying a beach day together, with a large ring visible on her engagement finger.

She chose to ignore the rumour-inducing jewellery and simply captioned her shot: ‘It’s the lil quiet moments that matter the most…’

However, sources have since claimed the pair are in no rush to walk down the aisle, telling Us Weekly: ‘They were ready to get married early on and talked about it.

‘But Jennifer decided she wants to do it differently this time. She’s been down the marriage road and doesn’t know if she wants to do it again.’

Besides, Jennifer and Alex ‘already act like they’re married’, according to a second source.

The insider added: ‘They’ve been combining their finances. They are very happy and have a great relationship. They’re committed to each other and their families, and that’s what matters most.’
