Jennifer Lopez and rumored beau Bradley Cooper are turning up the heat on their new romance.

Since making headlines with their romantic dinner in New York City's Per Se restaurant in September, Cooper, 36, has been wooing his new lady friend, Us Magazine reports.

He has been after Jennifer, calling her, for ages, a source told the magazine.

They've been talking on the phone and texting a lot, another source confirmed.

Lopez, 42, and Cooper were spotted again on Saturday, when the couple drove from his Pacific Palisades home to her Hidden Hills mansion.

After their date in New York, Bradley and Jennifer stayed in touch . . . she does like his attention, and it makes her feel good that he seems so into her. She has a fun time with Bradley and he makes her laugh, a source close to Lopez told People.

News of Lopez's new romance comes just three months after the singer announced the end of her seven-year marriage to Marc Anthony. The couple share custody of their three year-old twins, Max and Emme.

Sometimes it doesn't work -- and that's sad. But I remain an eternal optimist about love. I believe in love, Lopez told Vanity Fair in August.

I will always respect Marc as a singer and performer... he will always be in our lives. He will always hold a special place in my heart as the father of my children, she added.

Despite being spotted by photographers last weekend, Lopez and Cooper have been flying low on the radar with their budding romance, using disguises, arriving at events separately and meeting up in remote places like the New Jersey countryside, The Chicago Sun-Times reports.

Cooper, most famous for his roles in The Hangover films, recently finished filming the drama The Words with Olivia Wilde and Jeremy Irons.

Lopez is expected to return for another season of American Idol.
