Marc Anthony can hardly bear to spend a night away from his stunning new girlfriend, Shannon De Lima .
Just weeks ago he introduced the statuesque Venezualan model to the Beckhams.
And after taking her to the Country Music Awards at the weekend, the brunette was again by his side on Monday.

Shannon was a stunning support act as she and her man attended Lionel Richie 's star-studded tribute concert in Las Vegas
And Marc – who recently separated from Jennifer Lopez – took to the stage to perform a rousing rendition of the pop legend's moving ballad Endless Love.
Also present at the concert was Lionel's proud daughter, Nicole.
The mum-of-two was the epitome of elegance in a flowing patterned gown with her hair swept into a chic up'do.
At one point a beaming Nicole joined her father on stage as the pair addressed the crowd from his piano.
The reality TV star is currently blooming in her role as a mentor on the US show Fashion Star, and she recently described her dad as her "biggest mentor".
Country music power couple Faith Hill and Tim McGraw also lent their support on the night, which was held by the Academy of Country Music awards.
