Jennifer Lopez is reportedly 'sick and tired' of turning down Casper Smart's proposals.

The 46-year-old singer recently rekindled her relationship with toyboy Casper after an eight-month split.

And while the pair's romance appears to be going from strength to strength, Casper's desire to take Jennifer down the aisle is said to be angering the mother-of-two.

'Jen finally snapped at Casper by ordering him to stop proposing because she's sick and tired of saying no,' a source told Life & Style magazine.

Casper, 28, is apparently persevering in his pursuits despite his girlfriend's upset. The insider added the choreographer-and-actor hasn't let Jennifer's refusals put him off planning a new proposal.

'He's probably asked her at least five times this year alone!' the source added.

Jennifer is no stranger to weddings, having previously been married to waiter Ojani Noa, back-up dancer Cris Judd and fellow singer Marc Anthony.

Her divorce from Marc, who is father to her two children Max and Emme, was finalised in June 2014.

She later credited Casper for helping heal her broken heart following the split.

However, discussing the 18-year age gap between herself and Casper in a recent interview with Ellen DeGeneres, Jennifer insisted she hates it when she is labeled a 'cougar'.

"I'm not after younger guys," said. "If younger guys like me, then that's one thing."

Jennifer is currently working hard on her new TV show Shades of Blue, in which she plays a police officer, and preparing for her upcoming Las Vegas residency, which starts in January 2016.

And despite her busy schedule, Jennifer admits she and Casper always do their utmost to enjoy some alone time together.
"It's a lot of work, this business, but we do our best,' the singer told Entertainment Tonight.
