Let’s be honest. Everyone’s so excited that Britney Spears actually made it to this birthday that they keep celebrating her 27th over and over again. Talk about being stuck in Groundhog Day. But whatever keeps ol’ girl going strong is fine with us.

After receiving birthday wishes from Reese Witherspoon, Hugh Jackman and Taylor Swift during her visit to Good Morning America, Britney Spears spent the evening celebrating her big day with Lance Bass, Heidi Klum and other famous celebrity guests at Tenjune in NYC.

She was dressed demurely during a pre-taping of an appearance at the Rockefeller Center Christmas Tree lighting to take place today, but at the soiree last night, Brit flaunted some hefty boobage.

At least one of her birthday presents must have been some industrial-strength double-stick tape because the fact that her nipples never came loose is a Christmas miracle indeed.
