London, June 8: Christine Bleakley and boyfriend Frank Lampard were spotted heating up their romance as they enjoyed a holiday in Las Vegas earlier this week.

Christine, who showed off her slender figure in a blue and white polka dot bikini, couldn''t resist pulling her Chelsea midfielder for a series of kisses and cuddles as they basked in the sunshine before taking a dip in the hotel pool, reports the Daily Mail

And the feeling was most definitely mutual, as Frank cheekily kept grabbing his girlfriend''s pert posterior as they relaxed at their hotel.

It was reported last month that Frank is apparently planning a romantic proposal on board one of Chelsea owner Roman Abramovich''s luxury yachts.

Father-of-two Lampard, 32, is preparing to get down on one knee in Sardinia next week and ask for Bleakley''s hand in marriage. (ANI)
