Michael Strahan celebrated his 41st birthday Tuesday with a cake-filled night out with his “Live!” co-star, Kelly Ripa. Starting the night at Meatpacking hot spot Catch, a source says, the on-screen duo “looked like best friends.” “They were with a crew of 10 people,” added the spy. “They were sipping cocktails and toasting Michael with tequila shots.” The former NFL star was presented with a cake replica of himself topped with a Giants helmet in homage to his 15 years with the team and was overheard telling people he was “definitely taking home his head in cake.” Later, the group headed to PH-D at Dream Downtown with Ripa’s husband, Mark Consuelos, Tichina Arnold and more friends, and Strahan was given another cake. “As ‘Birthday Song’ by 2 Chainz and Kanye West played, Michael was given a Giants-colored cake in the shape of a football that read ‘Stomp Em Out!’ ” says a witness. We’re told Ripa and Consuelos looked “lovey-dovey,” while Strahan’s fiancée, Nicole Murphy, was out of town for the evening.
