Avril Lavigne Pregnancy Rumors Heat Up

rumors suggest were looking at a baby bump

Several photos captured of Avril Lavigne over the past few weeks have fueled speculation that the 28-year-old singer is pregnant.

In mid-May the Canadian entertainer hit several red carpet events with her fiance Chad Kroeger, a frontman for Nickelback.  They posed at the Billboard Awards on May 19, and she showed off a side profile view at 2013 Wango Tango on May 11.

The latest photo was captured in London earlier this week when she was leaving her hotel to go out to dinner in Mayfair.

Lavigne is reportedly planning a themed-wedding that she claims "will be quite spectacular."  She admits she has even withheld some details from the future groom.

Avril is concentrating on her 5th studio album, with one song left to write.  She hopes to release her latest body of work in September 2013.

Regarding the pregnancy rumors, several sources claim AL isn't pregnant.  Now that you've seen recent photos ... what do you think?
