Back in the swim of things: Bikini-clad Jennifer Lopez gets in shape for her movie return

While most people use a holiday as a time to relax, Jennifer Lopez spent the last weekend of her vacation getting in shape ahead of her return to acting.

After taking a lengthy break from movies to focus on her singing career and motherhood, J.Lo is set to resume her film career with a role in Love And Other Improvements this week.

Lopez, 38, and her four-month twins Max and Emme have been touring Europe with husband Marc Anthony over the last month.

After Anthony’s tour wrapped in Rome last Wednesday, the family and their entourage flew to Portofino in northern Italy for a few days R&R with designer pals Domenico Dolce and Stefano Gabbana.
