Latin superstar Marc Anthony has reunited with his ex-girlfriend Shannon De Lima and sparked rumours they are engaged after she was snapped wearing a diamond ring on her wedding finger.

The salsa singer ended his year-long romance with Topshop heiress Chloe Green last month (Feb14) and it appears he has already found love again with an old flame.

Anthony, 45, jetted to the Dominican Republic with Venezuelan model De Lima last week (ends14Mar14) and the beauty showed off her love for Jennifer Lopez's ex-husband by posting a series of snaps on Instagram.com.

Alongside one photo of the couple hugging, De Lima, 24, wrote, "Happy!!!! With my love", while she sports a sparkler on her left ring finger in another image, uploaded on Saturday (15Mar14), in which she cuddles her man on a sun lounger.

Neither Anthony nor De Lima have confirmed the engagement story, although the stunner posted a cryptic message on her Twitter.com blog on Tuesday (18Mar14). The note read: "Those who know don't say, those who say don't know".

The couple previously dated for a year in 2012 following his separation from Lopez in 2011.
