Never one to take herself too seriously, Adele delighted fans on Instagram by dressing up as an old woman the day after her 29th birthday.

"Nearly 30! Thanks for the well wishes. See you soon," the Grammy winner captioned a collage of four photos. In the pics, the mother-of-one wears a short wig, what appear to be prosthetics, and a pair of reading glasses to complete the illusion that she's aged considerably.

The "Hello" hitmaker's stomach is conveniently hidden in all of the images, which only raises speculation that she's expecting another kid with husband Simon Konecki. A source told Life & Style last month that the couple is ready to expand their family after welcoming son Angelo in October 2012.

“Adele is planning on having a second child and is actively trying to get pregnant,” the insider shared. Plus, she may be moving away from her native England. "Adele has spent a lot of time in LA over the years and thinks it is the perfect home base. California feels like a welcoming place.”

During one of her concerts last year, the blonde beauty told the crowd about her baby fever. "My womb is starting to ache a little bit," she admitted. "It's like, 'Baby, baby, baby. Need a baby, need a baby.' I'm not pregnant. I won't get pregnant until the end of the tour."

After kicking off the tour in Northern Ireland on Feb. 29, 2016, Adele has just four dates left — all taking place at the Wembley Stadium in London. The final performance will be played on July 2. Fans have barely seen the star since the last leg of her tour wrapped on March 26 in New Zealand.

With more than a month to go before she hits the stage again, we don't doubt that Adele has been keeping busy in her free time (wink, wink!)
