Lisa Appleton looked to be struggling with tennis on her recent vacation in Spain, throwing herself through the air and jabbing madly with her plastic bat.

The 48-year-old clearly put in a lot of effort as she tried to outsmart her companion, but her boobs almost slipped out of her bikini, to the amusement of onlookers.

Lisa was putting her ball skills to the test on a sun-drenched summer trip in Spain, where she is known for flashing the skin in a variety of unusual circumstances.

Lisa was being watched as she ran over the white sand by fellow beach goers, maybe not appreciating her attempts to hit a backhand while wearing an ill-fitting two piece.

Lisa rose to popularity on the 2008 edition of Big Brother, and has lately resurfaced in the spotlight owing to a succession of sexually revealing costumes.

She entered the famed mansion with beau Mario Marconi in the series.
