British newspaper The Sun reports that the ankle bracelet seems to be doing the starlet some good. She has recently been spotted voluntarily wearing the aparatus which monitors her alcohol intake to prove her sobriety. The 21-year-old was seen sipping nothing but Vitamin Water during the beach escapade.

And we wouldn't be surprised if the near-naked beach outing was all a plan to make ex-boy toy Calum Best rue the day he dumped her. British tabloids are all buzzing about Calum Best allegedly dumping Lohan because her post rehab days are a big bore. A source tells British newspaper the Daily Star, "Calum called Lindsay on [last] Friday and said that he was finding her post-rehab existence dull and that he didn't want to give up partying... Calum loves Lindsay, but he's simply not in the same place as her anymore."

If that's the case, then we applaud Lohan for her latest antic. No way, now how that red top isn't making Calum sweat as much as it's making us.
