Christina Aguilera shared news of her progressing pregnancy in a baby bump photo she posted this weekend on Twitter as she wished a happy summer to her followers. She is expecting a baby girl with fiance Matt Rutler whom she met several years ago on the set of her 2010 film Burlesque. Christina is already mom to 6-year-old son Max, her child with ex-husband Jordan Bratman.

In addition to wishing her fans and followers her summer greetings Aguilera showed off her expanding waistline. She also appeared to be touting the merits of EOS lip gloss for some reason–warning followers to keep their lips hydrated while in the summer sun. Since Christina manages to exude ample sex appeal even while several months pregnant, it’s pretty unlikely that fans will notice her attempt at promoting one of her favorite products, however–or that they’ll care that it appears her choice of flavor is mint.

“I’m really excited to meet our baby girl,” she told PEOPLE magazine during an interview earlier in June. “This has been a very easy and enjoyable pregnancy.”

Matt Rutler proposed to Christina Aguilera back in February after they found out she was pregnant. He was already planning to propose when they learned the exciting news.

Christina lost all kinds of weight before announcing her most recent pregnancy. She debuted her hot new body on The Voice, shocking fans with her incredible transformation. Hopefully she won’t find her hard work was all in vain once giving birth to her baby girl. Many moms find that their pregnancy weight is even harder to lose after having subsequent children.

Christina Aguilera won’t be returning to The Voice this fall when the show resumes airing in September. Gwen Stefani will be filling her shoes in the coach’s chair that Shakira occupied this past season.

Do you agree that even in the throes of a summer pregnancy Christina is still quite stylish and sexy?
