Jessica Simpson tweets about beau's 'perfect tush'

Washington, Jan 24 (ANI): Jessica Simpson seems to be completely smitten with her fiance Eric Johnson.

And there is one part in particular that she is very grateful for - his butt!, reports Radaronline.com.

"Thank you Lord for blessing me with a Man that has the perfect Tush," she had tweeted on Saturday night.

"Laying my hands upon it with peace:)," she also posted.

Simpson seems to have a thing for backsides. She had a hit in 2008, 'Push Your Tush', and she frequently commented on former boyfriend Tony Romo's derriere in his Dallas Cowboys uniform.(ANI)
