Jessica Simpson had two reasons to celebrate on Thursday – the newlywed was ringing in her 34th birthday, and enjoying the start of her honeymoon.
The blonde beauty, who married former NFL player Eric Johnson on Saturday, looked relaxed and rested as she shared her first post-wedding selfie.
"And the sun sets on 33," Jessica captioned the Instagram picture of herself striking an ethereal pose as dusk set in.
The singer and fashion designer seemed to be enjoying the balmy evening as she sat under a cabana, soaking up the summer heat in a patterned halter neck top.
The bare-faced beauty cut an elegant figure, just as she did on her wedding day when she stunned in a bespoke Carolina Herrera strapless gown. Her champagne-coloured wedding dress was embellished with gold sequins and described as "regal" by the Spanish designer.

It is not yet clear where Jessica and her new husband Eric, 34, are spending their honeymoon and whether they are with their children, two-year-old daughter Maxwell and one-year-old son Ace.
Jessica and Eric had previously had to postpone their nuptials due to the doting mum's near back-to-back births. When it came to her big day though, Jessica made sure that her kids played a starring role as a flower girl and ring bearer.
"Before I walked out, I kept hearing all the applause, so my kids got standing ovations!" Jessica told People of the moment before she walked down the aisle.

Her mother Tina and sister Ashlee, who is engaged to Diana Ross' son Evan, also acted as maids of honour.
"It's all about family for us," Jessica added. "The whole weekend has been completely magical for us. We've really built such a beautiful life, and it just keeps getting better."
It's a little princess!
