Jennifer Lopez is planning IVF treatment, according to US gossip magazine Star.
Jennifer, 43 - who has five-year-old twins, Max and Emme with her ex-husband Marc Anthony - is said to be worried that time is running out for her to extend her family with her new boyfriend Casper Smart. At 25, backing dancer Casper is 18 years J-Lo's junior.
A source says Jennifer is hopeful that 'with fertility treatments she'll be pregnant in the next couple of months'.
It is further claimed that the couple have put their wedding on hold after being unable to reach an agreement on a pre-nup contract. Despite this they are now said to be 'focused' on having a baby.
"They argued constantly over it, but Jen has decided to let the issue go and put her trust in him," the mole said. "She's more interested in trying for a baby than planning a wedding right now anyway - and Casper is completely on board."
The family friend claimed that Casper knows he is 'set financially for life if she has his baby', and that the couple will 'act surprised' when any news of a pregnancy breaks.
"They made a deal that when the pregnancy happens, Jen will make it sound like an 'oops' and a blessing at the same time, even though she's actually planned the whole thing."
The source also revealed that Jennifer was 'paranoid' about the public knowing she needed IVF to fall pregnant because it made her 'feel old'...
